Magnetism 1
Any material that attracts iron.
magnet
A type of stored energy
potential energy
True or false? Aluminum is a magnetic material
False
Nickel, Cobalt, Iron and Neodymium.
materials that are magnetic
This is what happens when a magnets north and south poles are brought near each other.
they will attract
The area around a magnet where magnetic forces act.
magnetic field
Energy in Motion
kinetic energy
A magnet that is easy to magnetize but will lose its magnetic properties quickly.
temporary magnet
This is what most magnets are made of.
iron
This is what happens when a magnets south and south poles are brought near each other.
they will repel
The two ends of a magnet are called this.
poles or magnetic poles
This is the effect of increasing the number of magnets
it will make the magnetic field stronger
A magnet that is hard to magnetize but stays magnetized.
permanent magnet
A substance that is attracted to a magnet.
iron
The interaction between electricity and magnetism.
electromagnetism
A force of attraction or repulsion between unlike or like poles.
magnetic force
This is how the Earth's magnetic field is similar to a magnet.
both have North and South poles
This is what happens when you break a magnet in half.
creation of two dipole magnets
This is what the two ends of a magnet are know as.
North and South poles
The parts of the magnet where the magnetic effects are the strongest.
magnetic poles
The strongest magnets in the world are made out of this.
Neodymium
A temporary magnet created by coiling a wire around a metal core, and passing a current through the wire.
electromagnet
This is what the source of the Earth's magnetic field is created by.
molten iron in the Earth's outer core
This is what Lodestones were used for by the Ancient Chinese and Greeks.
compass
The stone discovered by the Ancient Chinese and Greeks that would attract and magnetize iron.
