Magnets
This is the strongest place on a magnet.
What are the poles?
This is the pole the red north needle on a compass will point towards if placed on top of a bar magnet.
What is the south pole?
This is produced by a flowing electric current.
What is a magnetic field?
This is what turns kinetic energy into electric energy.
What is a generator?
This type of magnet best mimics the Earth's magnetic field.
What is a bar magnet?
This is the weakest point on a magnet.
What is the middle?
This is why when a compass is wrapped within a coil of copper wire that is connected to a battery the compass will change direction.
What is a magnetic field produced by an electric current?
Adding more coils, a bigger magnet, or more ferromagnetic material will do this to an electromagnet.
What is strengthening the magnet?
What turns electric energy into kinetic energy?
What is a motor?
This is the magnetic pole at the Earth's geographic south pole.
What is the magnetic north pole?
All magnets have this many poles.
What are 2 poles.
This is a region in which the magnetic fields of atoms are grouped together and aligned (going in the same direction).
What is a magnetic domain?
This is an advantage of an electromagnet over a permanent magnet.
What is the ability to turn it off?
This is what the conducting metal loop in a generator must move within to produce electric current.
What is a magnet?
This is where the Earth's magnetic field points to.
What is geographic north.
How can you turn a ferromagnetic material into a magnet?
What is rubbing it against a stronger magnet?
These lines go from north to south.
What are magnetic field lines?
These are the wire coils in an electromagnet.
What are solenoids?
This is the process of generating an electric current with a magnetic field.
What is electromagnetic induction?
This is the pressure in an electrical circuit that pushes the electrons through it.
What is voltage?
This is the invisible field around a magnet that will attract or repel other similar fields or ferromagnetic material.
What is a magnetic field?
This is what an electric current will do to a magnetic domain.
What is lining them up and creating a magnet.
This is what must be inside of the solenoid of an electromagnet to increase its strength.
What is a ferromagnetic core?
This is how electromagnetic induction works.
What is moving a coil or wire through a magnetic field?
This is the Danish scientist who first discovered that electric currents create magnetic fields.
Who is Hans Christian Oersted?
