Question

phys 1. Do a little research on your own and write definitions for the following: also list at least two elements or substances which are found in each of these three classes of magnetic materials. Diamagnetism Paramagnetism Ferromagnetism 2. Consider two parallel wires with the currents Ii and I2 running in opposite directions, the wires a) attract one another b) repel one another c) exert no forces on one another d) only exert a force on the wire carrying the least current e) only exert a force on the wire carrying the largest current

Explanation / Answer

1)Diamagnetic materials create an induced magnetic field in a direction opposite to an externally applied magnetic field, and are repelled by the applied magnetic field

Paramagnetism is a form of magnetism whereby certain materials are attracted by an externally applied magnetic field, and form internal,induced magnetic fields in the direction of the applied magnetic field

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. In physics, several different types of magnetism are distinguished

2) repel one another

3) negative

4)
