Magnets
What are the two types of magnets?
permanent and temporary
This is the equation for calculating the magnetic force on a moving charged particle.
What is F=qv x b?
The electric force can be calculated by multiplying the electric field times this.
what is the charge?
In order for charges to move they have to have a path to travel. This path is called a ________.
circuit
If the magnetic field is to the North and a positive charge is moving to the West the magnetic force would be in this direction.
What is down?
Magnets are most commonly made of what 3 materials?
iron, nickel, and cobalt
The is the equation used to determine the force from a magnetic field on a current carrying wire.
What is F = I"el" x B
These are the units of electric force.
What are Newtons?
The more of this the more current there will be through a circuit.
What is voltage?
If you want a positive charge moving upward to be forced east you would need a magnetic field in this direction.
What is south?
north pole, south pole
There would be no force from a magnetic field when a charged particle is moving in this direction.
What is parallel to the magnetic field?
Particles with _______ charges attract each other.
OPPOSITE
The more of this the less current there will be through a circuit.
What is resistance?
If an electron is moving north through a magnetic field to the East, the magnetic force would be in this direction.
What's up?
*Nothing much, what's up with you? ;)
What is the strongest and most commonly used rare Earth metal magnet is called the ________ magnet.
Neodymium
A charged particle moving in magnetic field perpendicular to is velocity would follow this type of path.
What is circular?
ElectrIcIty that moves and flows from one place to another Is called thIs.
what is current?
Resistors in parallel do this to the overall resistance.
If a particle moving North in a magnetic field going down into the ground is forced east it is this type of particle.
What is electron or negative?
What would happen if you cut a magnet in half?
You would have two smaller magnets that each have a north pole and a south pole.
The magnetic force does this much work on a moving charged particle.
What is zero, nada, zilch?
The system of two charges that are separated by using a force over some distance would have this.
Resistors in parallel have the same value for this.
What is voltage drop or potential difference?
in this situation there would be no force on the moving particle in a magnetic field.
what is motion parallel to the field?
