You get a battery, switch, nail and copper wire. You connect one end of the battery to the switch and the other end to the nail that is wrapped with some copper wire. The end of the switch that isn't connected you connect to the electromagnet.

Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
An electric field begins on north poles and end on south poles?
A magnetic field begins on the north poles and ends on south poles. An electric field begins at a positive charge and ends at a negative charge.
When the suns magnetic poles switch positions?
Great switch
Is the magnetic field of earth stronger near the equator of near the south pole?
The magnetic field is stronger at the poles.
The magnetic field of a magnet is strongest?
near both its poles
Force of pushing or pulling between magnetic poles?
This is the Electromagnetic force. (Technically, it's the Lorentz force, which is the force on a charge due to an electromagnetic field, but either will do.)
How does the process of electromagnetic induction work?
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.

Does gravity have a stronger pull at the eatrh poles then it does on the equator?
no, but the electromagnetic field of the earth does.
When are Earth's poles expected to switch?
Earth's poles are to switch every few hundred thousand years.
An electric field begins on north poles and end on south poles?
A magnetic field begins on the north poles and ends on south poles. An electric field begins at a positive charge and ends at a negative charge.
Is earths magnetic field weakest at its poles?
No, but at the poles the field (because of the orientation of the field lines) offers the least protection.

No, but at the poles the field (because of the orientation of the field lines) offers the least protection.
What determines the direction of polarization of a radiated electromagnetic field?
The polarization of an electromagnetic field is defined as the direction of its E field (electrostatic).
What are facts about electromagnetic fields?
An electromagnetic field is a physical field produced by electrically charged objects. The field can be viewed as the combination of an electric field and a magnetic field. The electromagnetic field may be viewed in two distinct ways: a continuous structure or a discrete structure.
When the suns magnetic poles switch positions?
Great switch
When electric and magnetic fields both exist it is called an?
Not really. You could have both an electric field and a magnetic field occupying the same space at the same time but they wouldn't 'make the definition' of electromagnetic until they began to fluxuate in phase at a harmonized frequency.
