Electromagnetism

Question 1

How to convert to Kelvin

Answer 1

Celsius + 273

Question 2

Protons

Answer 2

Positive charge

Question 3

Electrons

Answer 3

Negative charge

Question 4

Repel/Attract

Answer 4

Opposite signs attract, same signs repel

Question 5

Special Relativity

Answer 5

The faster an object moves the more its length gets contracted in the direction of motion

Question 6

How does a magnetic field form?

Answer 6

An electric charge moves

Question 7

Electromagnet

Answer 7

Object that behaves like a magnet due to an electric current

Question 8

Permanent Magnets

Answer 8

Objects that naturally have a magnetic field

Question 9

Electric and Magnetic Fields

Answer 9

Inseperable, one is the origin of the other

Question 10

Electromagnetic Field Principles (Maxwell’s Equations)

Answer 10

1) An electric charge acts as a source for the electric field
2)Stand alone magnetic charges can’t exist (objects always have north and south pole)
3) A disturbance in the magnetic field affects the electric field
4) A change in the electric field causes a disturbance in the magnetic field, creates a cycle with 3

Question 11

induction

Answer 11

A change in magnetic field can induce an electric current running through a wire
