Electromagnetism
100

the charge of electrons

What is negative charge?

100

any material that attracts iron, nickel, or cobalt

What is a magnet?

100
the build up of charges on an object
What is static electricity?
100

when unlike poles pull toward each other

What is attraction?

100

an electric current produces a magnetic field, or vice-versa (a magnetic field produces an electric current)

What is electromagnetism?

200

the charge of protons

What is positive charge?

200

the area of the magnet where the magnetic force is strongest

What are the magnetic poles?

200
when electrons move from one uncharged object to another by rubbing
What is friction?
200
when like poles of two magnets push away from each other
What is repulsion?
200

1. Increase electrical current

2. Get a larger iron core

3. Wrap more coils of wire around the solenoid

What are three ways we can increase the strength of an electromagnet?

300

the flow of electrons

What is electricity?

300

the attraction or repulsion between magnetic poles

What is magnetic force?

300
when electrons move from a charged object to another by direct contact
What is conduction?
300

a type of magnet that does not stay magnetized if it is heated or dropped

What is a temporary object?

300

This type of electromagnet converts mechanical energy into electrical energy

What is an electric generator?

400

the attraction or repulsion between electric charges

What is electric force?

400

a group of atoms that have their magnetic fields pointing in the same direction

What is a magnetic domain?

400
when electrons move to one part of an object due to the electric field of another object without touching
What is induction?
400

the AREA of magnetic force around a magnet in which objects are attracted or repelled

What is a magnetic field?

400

This type of electromagnet turns electrical energy into mechanical energy

What is an electric motor?

500
a region around a charged object in which electric force occurs
What is electric field?
500

The magnetic poles line up within their domains in order to magnetize an object

What causes the magnetic field?

500
the loss of static electricity as charges move from one object to another
What is static discharge?
500

imaginary lines used to show a magnetic field

What are magnetic field lines?

500

The form of static electricity transfer that occurs when a magnet is moved through a solenoid to produce an electric field

What is electromagnetic INDUCTION?
