Write some activities that you observe in your team to demonstrate magnetic force |
|
Answer» Playing with magnets is a safe and fun way to introduce students to physics. Simply put, magnetism is a force that attracts or repels magnetic objects. Magnets produce an invisible magnetic field and attract objects made of nickel, iron and cobalt. They also have two poles - the North Pole and the South Pole - and the opposite poles of two magnets always attract each other. Even the earth is magnetic, as it is jam-packed with molten rocks rich in magnetic materials such as iron. Earth behaves as a giant magnet, causing the north pole of a magnet to point roughly toward its own north pole. Are you ready to explore magnetic forces with your students? Try the simple activities below to get STARTED: 1. Repel or Attract? WANT to teach the basics of magnetism? Start by having students test to see which items or materials are magnetic and which ones are not. They can simply venture around the classroom to begin EXPLORING. When testing two magnets, they can also identify their two poles (north and south) by observing whether the magnets attract or repel each other. To get started, CHECK out this First Experiments Magnetism Set. It comes with a variety of magnets, including a super magnet, magnetic marbles, a horseshoe magnet and a compass magnet. 2. Make Your Own Compass Before there were navigation systems and Google Maps, people would use a compass if they got lost or to find their destination. The metal needle in the compass points to “magnetic north,” as it aligns with the Earth’s magnetic field. When using a compass, first make sure the needle lines up with the north-south axis and you can easily determine which way you need to go (with the help of a map), whether it’s north, south, east or west. You can make your own compass to observe how this magnetic tool works! To begin, you will need the following materials: Sewing needle Magnet (with a “north”/“south” distinction) Wax paper Scissors Red Sharpie marker Bowl Water When you’ve created your simple compass, place it in a bowl of water, allowing it to float on the surface. Once floating in the water, Earth’s magnetic field (caused by the magnetic materials nickel and iron in the Earth’s core) pulls at the opposite poles of the needle and aligns it with the north-south axis. Check out the Ultimate Vortex Generator to explore magnetism, vortexes, centripetal force and more! 3. DIY Magnetic Slime Slime is all the rage these days, and magnetic slime is double the fun! To conduct this experiment, you will need the following items: 8-oz white school glue Borax Large mixing bowl 9-oz plastic cup Measuring cups and spoons Zipper-lock plastic bag Iron filings Neodymium magnet Water Spoon Dinner plate Once you create the slime and smooth it evenly on the plate, bring the magnet close to the surface and observe what happens. The iron filings mixed into the slime causes it to be magnetic, and the slime will spring upward to grab the magnet. You can even use the magnet to create mini volcanoes in the slime. Also, note that the iron filings never leave the slime. Although the magnet is strong, the slime holds on to the iron filings by adhesion, a force that holds MOLECULES of different substances together. Magnetism is a cool phenomenon that students will love exploring! Try these activities to introduce them to the science - and fun - of magnetic forces.

Write example of 10 in state of rest and 10 in state of motion ? For class 9th standard for project? |
|
Answer» Answer:The branch of MECHANICS which deals with the motion of objects is called kinematics. If a body does not change its position, it is said to be on rest and if it changes its position it is known as motion. The examples of motion include: running, cycling, jumping, swimming, eating, drinking, playing, writing, typing, moving cars, throwing BALL. The examples of rest include: sleeping, sitting, standing, STARING, lying, a fixed clock, bottle kept on a table, a STOPPED car.Answer:The branch of mechanics which deals with the motion of objects is called kinematics.

Check Point 04 1 Name the lens which always forms a virtual image of an object.2 Discuss the case when a convex lens forms a virtual and enlarged image.3 which lens would you prefer to use while reading small letters from a dictionary?4 What type of lens is an air bubble inside the water?5 A convex lens is immersed in a liquid of refractive index greater than that of glass. How will the nature of lens change?6 A convex lens of focal length 20 cm can produce a magnified virtual as well as real image. Is this a correct statement? If yes, where shall theobject be placed in each case for obtaining these images? if u know then answer otherwise I will report don't spam answer fast |
|
Answer» 1. CONCAVE lens are used which always form virtual IMAGE of an OBJECT as it is used for short sightedness in which person can see close object very clearly but unable to see far objects it's also CALLED nearsightedness.3. convex lens will be used in the case of reading small words in a dictionary.as through it we can see NEARBY object very clearly and magnified.5.the nature of lens change to concave lens as it will start diverging the rays rather than focusing them on point. |

Plz help me....Its urgent.... |
|
Answer» Car A has travelled more.Since the graph is a straight LINE and has not CHANGED its direction, the BODY is travelling without changing its direction and the VELOCITY here can be considered as speed. So the distance travelled will be the area under the CURVE, which is definitely more in curve A.Distance travelled by A is ((25*10)+(1/2*25*10))=375m.distance travelled by b is (1/2*10*50)=250m. |

Answer» When there is a current in a wire, a circular magnetic field is PRODUCED around the wire. This magnetic field can deflect the needle of a magnetic compass. The strength of the magnetic field is GREATER:closer to the wireif the current is increasedWire runs VERTICALLY, current FLOWING bottom to top. Magnetic field rotates ANTICLOCKWISE. Second wire runs vertically, current flowing top to bottom. Magnetic field rotates in a clockwise direction. |
