Magnetic field strength, ………………., flux …………………represents the same quantity.

A magnetic needle oscillates in a uniform magnetic field of strength B1, with a time period of 10 seconds. The same magnetic needle oscillates in another uniform magnetic field of strength B 2 with a time period 20 seconds. Which magnetic field is strong, B1, or B2,? Why?

If a bar magnet moment M is freely suspended in a uniform magnetic field of strength field of strength B, then the work done in rotating the magent through an angle theta is

If a bar magnet moment M is freely suspended in a uniform magnetic field of strength field of strength B, then the work done in rotating the magent through an angle theta is

Statement-1: Magnetic field strength at a point on axial line of a bar magnet is along South to North pole of magnet. Statement-2: The magnetic field strength can never be along North to South pole of magnet.

Assertion: Magnetic field strength at a point on axial line of a bar magnet is along South to North pole of magnet. Reason: The magnetic field strength can never be along North to South pole of magnet.

Assertion Magnetic flux and the electric flux have the same units. Reason Flux passing throught a surface gives an idea about the field lines crossing that surface
