This is a temporary magnet created by an electric current.
What is an Electromagnet?
Exerts an invisible force called magnetism.
What is a magnet?
Electric motors are devices that use blank to convert electrical energy into kinetic energy.
What is electromagnets?
This (hopefully) everyday hygienic object uses an electromagnet to power the brush and clean teeth.
What is an electric toothbrush?
What would increasing the number of coils in an electromagnet do?
What would increase the strength of the object?
A bar made out of ferromagnetic material with a current running through it.
What is a solenoid?
Wire connected to a battery and wrapped around a magnetic material.
Increasing the number of turns in the coil would change the blank of the electromagnet.
What is the strength?
This item uses electromagnets to convert electrical signals into sound waves.
What are headphones?
If you break a magnet in half, how many poles will one half of the magnet have?
What is two poles?
Devices that use electromagnets to convert electrical energy to kinetic energy.
What is an electric motor?
A loop of wire is placed in a magnet. The wire is connected to a rotating shaft that when rotates causes the loop of wire to rotate within the magnet. What is this?
What is an electric generator?
The magnetic field around a single straight line is too blank to pick up paper clips.
What is too weak?
An electric motor is found in this household machine that sucks up unwanted messes from the floor.
What is a vacuum?
What is the most magnetic material?
What is neodineum?
The flow and amount of electricity in an electric circuit.
What is an electric current?
Two objects rub against each other causing charges to transfer from one object to the other.
What is static electricity?
An electromagnet is blank coiled or wrapped around a bar of magnetic material.
What is wire?
This item uses electromagnets to spin a coil of wire connected to the object's blades, causing them to rotate.
What is a fan?
When you pull a magnet slowly away from a magnetic material what happens to its magnetic force?
What is a magnetic domain?
This works by creating a magnetic field between two copper coils.
What is wireless charging technology?
In a non-magnetized material, blank are aligned randomly and cancel each other out.
What are magnetic domains?
This machine uses electromagnets to scan tiny details in the human body.
What is an MRI machine?
What does increasing the power of a battery do in an electromagnet?
What does increase the strength of the elctromagnet?
