Permanent bar magnet has a field strength

Reference no: EM13658551

A permanent bar magnet has a field strength of 1T. Assume we have a circular wire loop of radius R=0.50 cm that is carrying a current of I Amperes. What current is needed to make a magnetic field at the center of the wire loop that is equal to the field of the bar magnet?
