Question

The component of the magnetic field along the line op at the point p due to the bar magnrt

Answer 1

The component of the magnetic field along the line OP at the point P due to the bar magnet of magnetic moment 1.732 Am2 is as follows,

Br=ц₀/4π . 2 M cos∅ / r³

=10⁻⁷*2*1.732*cos 30 / 1³

=3*10⁻⁷ T

I hope the answer is satisfactory.
