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