Magnets and Magnetic Fields
Definition of ferromagnetic materials.
Strong attraction occurs between adjacent atoms, creating large groups of atoms whose net spins are in the same direction.
What unit is used to measure electric charge?
Electric charge is measured in coulombs.
How are magnets used in real life transportation?
They are used in mag-lev(magnetic levitation) trains and trams.
No, magentic fields do not actually begin or end.
What is the alternative right-hand rule?
A method for finding the direction of a magnetic force.
How are magnets used in hospitals?
The are used in MRI machines.
How is Magnetism triggered?
Magnetism is triggered by the movement of electric charges such as positive and negative
What is equation for magnetic force?
The equation for magnetic force is a positive test charge times its velocity times the magnetic field.
Will a magnet still have 2 poles if you cut it in half?
Yes it will because magnets always have 2 poles.
