Question

explain the method of preparing electromagnetic . how do test the poles of an electromagnet with the help of magnetic compass​

Answer 1

Answer:

Explanation:

electromagent can be prepared by regular conductor being wound around a wire which has current flowing through it . For better result they place a solenoid in it.

They test the poles with a magnetic compass with the help of snow rule which was found by Henry Oersted.

s-south

n-to north

o-compass placed over the wire

w-deflects to west.

Answer 2

Explanation:

For making an electromagnet we use the property of current that every current carrying conductor produces a magnetic field around it in a plane perpendicular to the direction of current concentric to the wire.

The direction of the magnetic field thus produced is determined by the Maxwell's right hand thumb rule. In which the direction of thumb is in the direction of the current and the curves fingers denote the direction of the magnetic field.

So, we warp a soft iron with an insulated copper wire encircling it closely and connecting the two ends of this coil with a direct current source.
