Year 2- Fields

Question 1

what is a field

Answer 1

a region where an object experiences a non contact force

Question 2

3 main types of fields

Answer 2

magnetic, electric, gravitational

Question 3

what has a magnetic field

Answer 3

any magnet (permanent magnetic)
magnetic materials (iron, cobalt and nickel) will become induced magnetic when in the field of a permanent magnet

Question 4

what has an electric field

Answer 4

any object with charge, in which a charge will experience a force

Question 5

what has a gravitational field

Answer 5

any object with a mass
any mass will experience a force

Question 6

where do field lines point in a magnetic field

Answer 6

north to south

Question 7

where do the field lines point in an electric field

Answer 7

positive to negative

Question 8

where do the field lines point in a gravitational field

Answer 8

towards the mass, it is an attractive force

Question 9

how can you represent greater forces using field lines

Answer 9

they will be more closely packed together, therefore showing greater field strength

Question 10

how are field lines represented in a uniform field

Answer 10

straight
parallel
evenly spaced
pointing in the same direction
THE FIELD STRENGTH IS THE SAME AT ANY POINT

Question 11

how are field lines represented in a radial field

Answer 11

evenly spaced, pointing towards the centre of the object
the field strength decreases as you move away from the centre of the field
