What is magnetic field intensity?

State unit of magnetic field intensity.

The dimensions of magnetic field intensity in M,L,T and c(coulomb) is given as

If a 10 m long metallic bar moves in a direction at right angle to the magnetic field with a speed of 5.0 m s^-1 25 V e.m.f. is induced in it. Find the value of magnetic field intensity.

What is magnetic dipole? Derive an expression for magnetic field intensity at a point on the equitorial line of a bar magnet.
