Electricity and magnetism
Electromagnetism is everywhere. It is a field that exists throughout space. When particles are electrically charged, the electromagnetic field exerts a force on them. These particles then move and exert a force on the electromagnetic field. By generating these fields when and where we want them and by controlling these forces we get electricity. This gives us the power we use in the modern world. AD our TVs, phones, street lights and cars depend on electromagnetism.
So what is electromagnetism? Actually, it is two things, but they are so closely connected that it is convenient for us to think of them as one, as two sides of the same coin. There are two types of field: electric and magnetic. Electrically-charged particles result in an electric field, static electricity. When there is a conductor, a material which will allow electric field to pass through it, then we can create an electric current. In our homes, the conductors are the wires that run through our house to the light bulbs or the TV. A magnetic field results from the motion of an electric current and is used to generate the electricity we use.
In the 19th century, James Clerk Maxwell, the first Scottish physicist, produced the equations proving that two forces acted as one. One effect of this was for physicists all over the world to hurry back to their libraries and laboratories to rewrite the theories on the motion of objects. Maxwells equations showed that what physicists had believed for centuries was in fact not correct. It was not until Einstein, in the 20th century, that the theory of motion was put right - at least for now....

a) exerting a force b) creating electromagnetic fields c) charging particles. d) moving particles.

2. Electrical and magnetic fields...
a) are opposites. b) are two very different things. c) are very closely related. d) need a conductor.

3. Maxwell's equations...
a) corrected the theory of motion. b) caused scientists to change their opinion. c) rewrote older theories. d) have completely ensured the theory of motion now.

4. Our modern knowledge of electromagnet comes from...
a) Ampere. b) lightning. c) Benjamin Franklin. d) experiments with magnets.

5. The electric battery....
a) could operate a machine. b) could create an electric current. c) was invented by Faraday. d) was invented in 1800.
