Static Electricity #1
the charge of electrons
What is negative charge?
any material that attracts iron, nickel, or cobalt
What is a magnet?
when unlike poles pull toward each other
What is attraction?
an electric current produces a magnetic field, or vice-versa (a magnetic field produces an electric current)
What is electromagnetism?
the charge of protons
What is positive charge?
the area of the magnet where the magnetic force is strongest
What are the magnetic poles?
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?
the flow of electrons
What is electricity?
the attraction or repulsion between magnetic poles
What is magnetic force?
a type of magnet that does not stay magnetized if it is heated or dropped
What is a temporary object?
This type of electromagnet converts mechanical energy into electrical energy
What is an electric generator?
the attraction or repulsion between electric charges
What is electric force?
a group of atoms that have their magnetic fields pointing in the same direction
What is a magnetic domain?
the AREA of magnetic force around a magnet in which objects are attracted or repelled
What is a magnetic field?
This type of electromagnet turns electrical energy into mechanical energy
What is an electric motor?
The magnetic poles line up within their domains in order to magnetize an object
What causes the magnetic field?
imaginary lines used to show a magnetic field
What are magnetic field lines?
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?
