Question

True or False a) Ampere's Law can be used to develop the formula for themagnetic field around a long straight wire with a current in thewire. b) Copper and Aluminum are non-magnetic materials. c) The torque on a loop on a loop of wire with a current in itis directly proportional to the magnetic flux through thecoil. d) Current is in the direction of movement of positive chargesso that the right hand rule works for force on a wire with acurrent just like a moving positive charge.
