Vocabulary Review-Magnetism

Magnetic domain A microscopic cluster of atoms with their magnetic fields aligned

Faraday’s Law Induced voltage in a coil is proportional to the product of the number of loops and the rate at which the magnetic field changes within those loops

Magnetic Field A force field that fills the space around every magnet or current carrying wire

Electromagnetic Induction The phenomenon of inducing a voltage in a conductor by changing the magnetic field near the conductor

How can you ruin a magnet? Drop it Heat it Store it improperly

Magnetic Poles

If you suspend a bar magnet from its center it will act as a c________

North and South Poles- all magnets have them The end that points north (means north seeking) and is called the north pole The end that points south (means south seeking) is called the south pole

Does it make sense that the north pole of a magnet can be attracted to the north pole of the earth?

A north magnetic pole never exists without a south pole =

Magnetic Fields

The space around a magnet is where the magnetic force is exerted The field lines are always drawn from N______ to S_________ North to South

Draw the magnetic lines of force around the bar magnet

How can you determine where the strength on a magnet is stronger? The lines will be closer together where they are stronger
