The type of force a magnet exerts on another magnet.
What is magnetic force (or electromagnetic force)?
100
He discovered the relationship between electricity and magnetism.
Who is Oersted?
100
This is the process of generating current by moving an electric conductor relative to a magnetic field.
What is electromagnetic induction?
100
These are THREE ways to increase the magnetic field in a solenoid.
What are increase the current, add more coils, or insert a ferromagnetic core (like an iron rod)?
100
This is a device that can change the voltage and current in two linked circuits.
What is a transformer?
200
Where a magnetic field is strongest.
What is near the poles of a magnet?
200
These two things generate magnetic fields.
What are permanent magnets and moving charges?
200
He discovered electromagnetic induction.
Who is Faraday?
200
This is what all galvanometers use a solenoid to do.
What is measure current?
200
This is the only type of current that a transformer works with.
What is AC or alternating current?
300
This is how magnetic field lines are drawn.
What is from north pole to south pole.
300
If a current-carrying wire is going down through the center of a clock, this is the direction of the magnetic field lines around the wire.
What is clockwise?
300
This is the type of current generated by moving a magnet in and out of a coil of wire.
What is alternating or AC?
300
This is the type of ring in an electric motor.
What is split ring or commutator?
300
This is the type of generator used in most large power plants today.
What is AC?
400
This is the magnetic declination in Santa Cruz with direction to the nearest degree.
What is 13° east?
400
If the magnetic field lines are going up and a charge is moving away from you, this is the direction of force on that charge.
What is to the right?
400
This is a device that converts mechanical energy into electrical energy by rotating a coil of wire in a magnetic field.
What is a generator?
400
This is how a loudspeaker is built.
What is with a solenoid placed around one end of a permanent magnet?
400
This is the main source of electrical energy in American power plants today.
What is (burning) coal?
500
These are aligned in a magnetized ferromagnetic material.
What are magnetic domains?
500
This is a name for a current-carrying coil.
What is a solenoid?
500
This type of generator is built most similarly to an electric motor.
What is DC?
500
This type of generator has solid rings (not split rings or commutators).
What is AC?
500
This is the output current from a transformer with 15 coils in the primary coil, 60 coils in the secondary coil, an input voltage of 120 V, and in input current of 10 A.
