Magnets and Magnetic Fields

Question 1

What has poles?

Answer 1

Magnets

Question 2

How many poles does these magnets have?

Answer 2

2

Question 3

What are the two poles called?

Answer 3

North and South

Question 4

Where is it called when magnets and other magnetic materials in a region experience a force?

Answer 4

Magnetic Field

Question 5

What way does the magnetic field lines go?

Answer 5

From north to south

Question 6

What does the way of the lines show?

Answer 6

It shows the way of another force acting upon the north pole would be at each part of the field

Question 7

The closer the lines are together shows what?

Answer 7

That the magnetic field is stronger at this part

Question 8

What part of a magnetic field would be the strongest?

Answer 8

At the poles

Question 9

If the magnetic field is strongest at the poles what would this mean for magnetic forces?

Answer 9

They are also strongest at the poles

Question 10

What are like poles

Answer 10

Poles that are the same like south poles and south poles

Question 11

What happens when like poles meet or are near each other?

Answer 11

They repel

Question 12

What is an unlike pole?

Answer 12

Poles that aren’t the same like north with south

Question 13

What would happen when unlike poles are near each other?

Answer 13

They are attracted to one another

Question 14

Name the characteristic of the magnetic field of an unlike pole.

Answer 14

Uniform field

Question 15

What is a uniform field and how would you draw this?

Answer 15

Lines are attracted to each other and so connect. They would be drawn with at least three parallel lines same distance apart and curved lines to each poles

Question 16

Between the poles what are the strengths like different or the same?

Answer 16

Same

Question 17

What do you need to find the magnetic field of a magnet?
(5 things)

Answer 17

-compass and its needle
-Magnet
-paper
-pencil

Question 18

Which way does it go:
A. Mark direction of compass needle by drawing two dots- one at each end of the needle
B. Repeat this method at different points around the magnet to get several field lines.
C. Put the magnet on a piece of paper and draw around it
D. Move the compass so that the tail end of the needle is where the tip of the needle is in the previous position and put a dot by the tip of the needle. Repeat this and then join up the marks you’ve made. Having one field line around the magnet.
E. Draw arrows from North to South on field lines
F. Place the compass on the paper near the magnet. The needle will point in the direction of the field line at this position.

Answer 18

C
F
A
D
B
E

Question 19

What do compasses align the field lines with when there is no magnetic field given?

Answer 19

The Earth’s north pole

Question 20

Why does the compass move with the Earth’s north pole?

Answer 20

It generates its own magnetic field

Question 21

What is the north pole actually?

Answer 21

A magnetic south pole

Question 22

If the north pole in the earth is actually a magnetic south pole what does this mean?

Answer 22

That the core is magnetic
