SUBJECT: GENERAL PHYSICS 2

TOPIC: MAGNETIC FORCE AND MAGNETIC FIELD

1. A straight wire with length L carries a current I which is directed to the right and is perpendicular to an unknown uniform magnetic field B. A magnetic force Facts on a conductor which is directed downwards.

A. Determine the magnitude and the direction of the magnetic field in the region through which the current passes.

B. If the angle between the current and the magnetic field is O this time, what would be the new value of the magnitude of the new magnetic force?
