Question

Oersted is a unit of

• A. Dip
• B. Magnetic intensity
• C. Magnetic moment
• D. Pole Strength

Answer 1

The correct option is B

Magnetic intensity

The explanation for the correct option

In the case of option B,

1. Oersted is the$\mathrm{C}.\mathrm{G}.\mathrm{S}$ unit of magnetic field intensity.
2. Magnetic field intensity is the force experienced per unit pole at any point.

The explanation for the incorrect options

In the case of option A,

1. Dip is the angle made by the earth's magnetic field with respect to the horizontal plane, in the magnetic meridian.
2. It is the measure of an angle.

In the case of option C,

1. Magnetic moment is the product of the strength of either pole and the distance between the magnetic poles.
2. $\mathrm{Weber}$is$\mathrm{S}.\mathrm{I}\mathrm{unit}$ of the magnetic moment.

In the case of option D,

1. Pole strength is defined as the strength by which magnetic materials can get attracted towards the magnet.
2. $\mathrm{Ampere}-\mathrm{meter}$ is$\mathrm{S}.\mathrm{I}\mathrm{unit}$ of the pole strength.

Hence, option B is the correct answer.
