Q. 205.0( 1 Vote )

Write true or false for the following statements:

The magnetic field produced by a current in a straight wire has no poles.

Answer :

True.

If we put a current carrying wire in a magnetic field perpendicular to its length, then it neither gets attracted or repelled by that field and hence these concentric circles neither have a starting point nor an ending point and the compass points tangential to the circles at every point.
