3. Electromagnets (Right)
What is an electromagnet?
2) What is a solenoid?
3) How do I make a solenoid?
4) What affects the strength of a solenoid?
Electromagnet: A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
2) Solenoid: wire wrapped around an iron core (nail). Electrons pass through the wire, making the electrons in the nail line up perfectly, creating a magnet (draw pic on board)
3) -Wrap some insulated copper wire around an iron core (nail).
-Attach a battery to the wire…
4) More coils = stronger magnet
Stronger battery = stronger magnet

4. Use the Brainpop! Video to define the following (on the LEFT)
Describe (tell all about)
Electromagnet
Solenoid
Magnetic field
Q: How is an EM different from a regular M?

5. Making a solenoid…
A solenoid is ________________________ ___________________________________. To make a solenoid you need the following three materials: ____________________, ________________, and ______________. First, you wrap the wire around the ________. Then you connect the wire to a _____________. The more coils of the wire, the ___________ the magnet. The stronger the battery, the ________________ the magnet.

6. Exit slip An electromagnet uses electricity to create a magnetic field
True b. false
2. What is the name for an electromagnet made from coiling wire around a nail and attaching to a battery?
_________________________
3. Magnets are created by the flow of protons
True b. false
4. The less coils of wire around the nail, the stronger the battery
a. True b. false
