Q1:

A 50 cm current-carrying section of wire is positioned at to a 0.2 T magnetic field. It experiences a force of 0.25 N. What is the strength of the electric current in the wire?

Q2:

The diagram shows a section of wire that has been positioned parallel to a uniform 0.1 T magnetic field. The wire carries a current of 2 A. What is the direction of the force acting on the wire due to the magnetic field?
