Let a bar magnet makes angle θ with magnetic field B and 2l be the length of the bar as show in figure. Force on N-pole = mB alo...

To demonstrate the similarity of a current carrying solenoid to a bar magnet, let us calculate axial field of a finite solenoid carrying ...

When we see a current carrying loop from top, current direction is anticlockwise and has north polarity. If, lower face of loop is seen f...

 

Magnetic dipole consists to two unlike poles of equal strength and separated by a small distance. The distance between the two poles o...

Magnetic field lines of a magnet form closed continuous loops. These lines are not discontinuous as of electric field. Outside ...

A space around a magnet or a conductor carrying current, in which force of attraction or repulsion on a magnet can be perceived is called...

Earth behaves as a magnet: This is as if a big magnet is held at the  center  of the earth with its north pole pointing towards ...
