The region in which magnetic forces act
An example of ferromagnetic material
Magnet has two ends, each one called____________
A cluster of billions of atoms that all have magnetic fields that are lined up in the same way.
The type of magnetic mineral found in nature.
The smallest particle of an element
It is one of about 100 basic materials that make up all matter.
The center of every atom is called__________
Nuclear particles that carry a positive charge
Tiny particles around the nucleus which carry a negative charge.
A device that has a magnetized needle that can spin freely.
What are the two magnetic poles of the Earth?
Does the compass needle point to the same place?
The region around the earth which acts like a magnet is called_____.
How is earth like a magnet?
A current-carrying coil of wire with many loops.
What is a solenoid with a ferromagnetic (made of iron) core?
What would happen if you increased the number of coils around a solenoid?
Why an electromagnet a temporary magnet?
How is an electromagnet different from a permanent magnet?
A scientist who discovered that magnetism and electricity are related.
The relationship between electricity and magnetism is called___________
What happens to a compass needle when current flows through a wire?
What flows through the wire when it is attached to the battery?
How does a flowing electric current create a magnetic field?
magnetic field
Iron
a magnetic pole
Magnetic Domain
Magnetite. Another is a lodestone
atom
Element
Nucleus
protons
electrons
compass
North and South magnetic poles
Yes, to the magnetic north pole.
Magnet field
Earth has a magnetic field and has a north magnetic pole and a south magnetic pole.
solenoid
Electromagnet
The magnetic field of the solenoid would be strengthened.
The temporary magnetic field of an electromagnet is produced by the current in the wire from the battery and the magnetized core.
Electromagnet can be turned on and off; its strength can be increased by adding loops of coil, using more current, or using a different core.
Hans Christian Orsted
Electromagnetism
The compass needle will move.
electric current
When electric charges(electrons and protons) flow through a wire, it moved thus causes magnetism/magnetic filed around the wire
