PES 1120 Spring 2014, Spendier


Today: - Force between two parallel, infinite wire currents - Ampere's Law - Solenoids. DEMO: We have seen that moving charges or currents are the source of magnetism. This can be readily demonstrated by placing compass needles near a wire.

Force between two parallel wires


This force between two current carrying wires gives rise to the fundamental definition of the Ampère: If two long parallel wires 1 m apart each carry a current of 1 A, then the force per unit length on each wire is 2 x 10- 7 N/m.

Magnetic fields | The force between two parallel wires


Parallel wires carrying currents will exert forces on each other. Each wire produces a magnetic field, which influences the other wire. When the currents in both wires flow in the same direction, then the force is attractive.

Magnetism Explained | Currents in the opposite direction


How does magnetism work and what is its relation to the electric force? In this chapter I will attempt to explain the relationship. First let’s look at some simple electrical experiments involving the magnetic force between current carrying wires
