Magnetic Field produced by current

Magnetic field produced by current B = (μo I)/(2πr) RHR #2 Thumb = current Fingers = location of field Palm = Direction of field

Two wires each 1m long are separated by a distance of 10cm Two wires each 1m long are separated by a distance of 10cm. The wire on the left has a current of 5A flowing down, the wire on the right has a current of 2A flowing up. What is the magnitude and direction of the force on the right wire from the left wire? 10cm 5A 2A

A square loop of wire with current flowing clockwise is placed next to a wire. The wire has a current of 5A flowing down. What is the direction of the net force on the loop from the left wire? 5A

Magnetic field produced by loop(s) B = N ((μo I)/(2R)) What is the magnitude and direction of the magnetic field produced inside of a loop of Radius 20cm with a counter-clockwise current of 10A flowing in it?

Magnetic field produced by Solenoid B = μo n I n=(# of turns)/length What is the magnitude and direction of the magnetic field produced inside of a solenoid of Radius 20cm, 200 turns and a length of 3cm with a counter-clockwise current of 10A flowing in it?
