The distance between the poles of a horse shoe magnet is 0.1 m and its pole strength is 0.01 amp-m. The induction of magnetic field at a point midway between the poles will be

The distance between the poles of horse shoe magnet is 10 cm and its pole strength is 10^4 A.m . Calculate the field at the point P midway between the poles.

The pole strength of a horse shoe magnet is 90Am and distance between the poles is 6 cm . The magnetic induction at mid point of the line joining the poles is,

Two poles of a horse shoe magnet each of pole strength 2 Am are 8 cm apart. Find the magnetic field intensity at the midpoint of the line joining the poles.

A bar magnet is 0.1 m long and its pole strength is 12 Am. Find the magnetic induction at a point on its axis at a distance of 0.2 m from its centre.

A bar magnet is 0.1 m long and its pole strength is 12 Am. Find the magnetic induction at a point on its axis at a distance of 0.2 m from its centre.

When a small piece of wire passes between the magnetic poles of a horse-shoe magnet in 0.1 sec, emf of 4 xx 10^(–3) volt is induced in it. The magnetic flux between the poles is :
