Explain the term Magnetic momentum.

Answer»

Magnetic moment, also known as magnetic dipole moment, is the measure of the object’s tendency to align with a magnetic field.  

“Magnetic Moment is defined as magnetic strength and orientation of a magnet or other object that produces a magnetic field.”  

The magnetic moment is a vector quantity. The objects have a tendency to place themselves in such a way that the magnetic moment vector becomes parallel to the magnetic field lines. The direction of the magnetic moment points from the south to the north pole of a magnet. The magnetic field created by a magnet is directly proportional to the magnetic moment.

Magnetic Moment Formula:

The magnetic moment is a vector relating torque of an object to the magnetic field. This is mathematically represented as:

τ = m × B

Where,

  • τ is the torque acting on the dipole
  • m is the magnetic moment
  • B is the external magnetic field

Magnetic Moment Unit:

In the definition for the current loop, the Magnetic moment is the product of the current flowing and the area, M = I A

  • So, the unit conferring to this definition is articulated by Amp-m2.
  • It can also be suggested in terms of torque and moment. Conferring to that, the torque is measured in Joules (J) and the magnetic field is measured in tesla (T) and thus the unit is J T -1.
  • So, these two units are equivalent to each other and are provided by 1 Amp-m2 = 1 J T -1.

Prisms are used in binoculars. Collect information about why prisms are used in binoculars.

Answer»
  1. Binoculars consists a pair of identical or mirror symmetrical telescope mounted side by side and aligned to point accurately in the same direction, allowing the viewer to use both eyes, when viewing distant objects.
  2. The prisms are used in a set of binoculars for image correction and keeping the binoculars small enough to be hand-held. 
  3. The prisms also serve to reduce the size of the binoculars. This is a result of their path bending qualities, as the light’s path curls through the prisms, the length of the instrument is reduced making it easier to handle.
  4. We get good image with more brightness.
  5. Objective size and optical quality should be increased by using prisms in binoculars.

Which one of the following methods of Capital Budgeting assumes that cash-inflows are reinvested at the projects rate of return ?

Answer»

Modified internal rate of return (MIRR) assumes that positive cash flows are reinvested at the firm's cost of capital, and the initial outlays are financed at the firm's financing cost. By contrast, the traditional internal rate of return (IRR) assumes the cash flows from a project are reinvested at the IRR. The MIRR more accurately reflects the cost and profitability of a project.
