Magnets
This is the strongest place on a magnet.
What are the poles?
This is what the 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 a bar magnet placed close to a compass can change the needle's direction.
What is the magnet is stronger/closer than the Earth's magnetic field.
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?
These are three advantages of an electromagnet over a permanent magnet.
What are the ability to turn it off, make it stronger, and change polarity ?
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 are the poles.
How can you turn a ferromagnetic (made of iron, cobalt, nickel) 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 person who is credited with discovering electromagnetic induction.
Who is Michael Faraday?
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 an iron 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?
