Magnet Masters
True or False The thickness of a material does not affect the magnetic field.
False
If two balloons are both negatively charged what would happen when they are placed together? Would they attract or repel?
Repel
You have an open circuit with wires, a light bulb, and a battery. You need to place something between the two wires to create a closed circuit. (to make the bulb light up)
conductor
I am the constant flow of electrons and need a power source. Am I static electricity or current electricity?
True or false Magnetic forces are always blocked by thin materials.
False
Which magnet depends on electricity and is temporary?
Electromagnet
What kind of electricity is a lightning strike? Static electricity or current electricity
Static Electricity
You have a closed circuit with a battery, wires, light bulb, and metal nail. What would happen to the light bulb if you replaced the nail with an insulator?
The bulb would not light up
I AM A MATERIAL THAT SLOWS DOWN OR DOES NOT ALLOW THE PASSING OF ELECTRICITY
INSULATOR
IN ORDER FOR ELECTRICITY TO FLOW THROUGH A CIRCUIT, THE CIRCUIT MUST BE ___________
What is CLOSED
What is the difference between a permanent magnet and an electromagnet?
A permanent magnet is always magnetic, the magnetic doesn't change, electromagnet can be turned on and off
If I have a closed circuit with 2 light bulbs, a battery, and wires, and switch that is turned on, would the lightbulb light up?
Yes, because wires connect to each light bulb and an on switch.
IF I HOOKED UP A CIRCUIT THAT CONTAINED 2 LIGHT BULBS, AND I THEN TOOK ONE OF THE BULBS OUT OF THE CIRCUIT, THE ELECTRICITY STOPPED FLOWING AND THE OTHER BULB WENT DARK. WHAT KIND OF CIRCUIT WAS I USING TO POWER THE LIGHTBULBS?
SERIES CIRCUIT
IF I WALKED ACROSS CARPET WEARING SOCK AND TOUCHED METAL AND FEEL A SMALL SHOCK WHAT IS THIS CALLED?
STATIC ELECTRICITY
The field around the nail in an electromagnet exists when the current (flows or stops) so these are called (temporary or permanent) magnets.
flows, temporary
True or false the distance between a magnet and a paper clip affects the magnetic force.
True
IF I HOOKED UP SOME SPEAKERS IN A CIRCUIT, AND AFTER A WHILE ONE OF THE SPEAKERS QUIT WORKING, BUT THE OTHER SPEAKER CONTINUED TO WORK, WHAT KIND OF CIRCUIT DID I HOOK UP?
PARALLEL CIRCUIT
The _____ _______ can be created around an iron nail wrapped with a copper nail. This is called an ________.
magnetic force, electromagnet,
True or False When a comb is rubbed with a wool cloth then held near paper the paper will attract because they have opposite charges.
True
