1.	Choose the incorrect statement.(A) Fleming's right-hand rule is a simple rule to know the direction of induced current(B) The right-hand thumb rule is used to find the direction of magnetic fields due to currentcarrying conductors(C) The difference between the direct and alternating currents is that the direct current alwaysflows in one direction, whereas the alternating current reverses its direction periodically(D) In India, the AC changes direction after every so second50
Answer» The right-hand rule is based on the underlying physics that relates magnetic fields and the forces that they exert on moving charges—it just represents an easy way for physicists to remember the directions that things are supposed to point. Occasionally a physicist will accidentally use their left hand, causing them to predict that the magnetic force will point in a direction opposite the true direction We can find the magnetic field that is caused by moving charges using a second right-hand rule. The magnetic field made by a current in a straight wire curls around the wire in a ring. You can find it by pointing your right thumb in the direction of the current in the wire and curling your fingers. Your fingers will be curled in the same direction as the magnetic field around the wire. so wrong statement is a)
