Q

What are capacitors?

A

Devices for storing charge

17
Q

What are resistors?

A

Electrical components that dissipate energy

18
Q

What kind of charges do magnetic fields surround?

A

Moving charges

19
Q

What also has a magnetic field?

A

Any material with permanent magnetism is surrounded by a magnetic field

20
Q

How does a magnetic field exert a force?

A

Exerts a magnetic force on a moving charge
-but not when the charge is moving in the same direction as the magnetic field

21
Q

What is magnetic induction?

A

It is the production of an induced electromotive force (EMF) across a conducting loop caused by a change in magnetic flux

22
Q

What is magnetic flux?

A

It is the total magnetic field which passes through a given area

23
Q

What does Faraday’s Law give you?

A

The magnitude of emf

24
Q

What does Lenz’s Law give you?

A

The direction of the induced current

25
In what direction does the current/emf induced by a changing magnetic flux point towards?
The direction is pointed to whatever opposes the change in flux
26
What is a simple harmonic motion?
Is a type of motion in which the restoring force on the moving object is directly proportional to the magnitude of the object's displacement
27
How does the restoring force act?
Acts towards the object's equilibrium position
28
What can waves be thought as?
As singular harmonic motion happening at different, connected points simultaneously
29
What are longitudinal waves?
The motion of the wave happens in the same direction as the direction of the wavelength
30
What are transverse waves?
The motion of the waves happen perpendicularly to the direction of the wavelength
