2. Energy and Magnetic Fields
Mar 6 / Act D 65 A
Energy and Magnetic Fields
LEARNING TARGET: I can diagram the magnetic field of a magnet to describe the changes in potential energy due to a magnet’s position.
CH Q
What are the properties of magnetic fields?
VOCAB:
Field electromagnetism
area where objects can interact without touching
(gravity, magnetic, electromagnetic)
magnetic fields making electricity
(and electricity making magnetic fields)

3. DISCUSSION
What are noncontact forces?
non-touching interactions that decrease with distance

5. (THEY LOSE THEIR MAGNETISM)
PROCEDURE AND DATA
MATERIALS:
PROCEDURE: Read on pg. D and summarize
DATA: Notes in journal
- drawings of magnetic fields on graph paper
DO NOT DROP MAGNETS !!
(THEY LOSE THEIR MAGNETISM)

6. debrief example

7. POST DISCUSISON
1. What are fields?
Silently read pgs. D74-75

8. 1. Compare and contrast the 3 types of fields.
POST DISCUSISON RDG.
1. Compare and contrast the 3 types of fields.
gravity =
jump up, pulled down
magnetic =
opposite poles attract (pull)
electric =
opposite charges attract (static electricity)
2. If a field is present there is also a force because...
of the noncontact interaction happening

9. magnets pull more as they get closer
POST DISCUSISON RDG.
3. Explain how a field gets stronger as the distance from the source decreases.
magnets pull more as they get closer
4. Explain the directional properties of fields.
up / down
north / south
positive / negative

10. ANALYSIS
- Discuss and answer Q 2 & 3 on pg. D 75
ANS CH Q
What are the properties of magnetic fields? A:
Properties of magnetic fields are:
1. there are two poles
2. opposites attract – like repels
3. field strength decreases with distance
