Simple phenomena of magnetism — practice question
A student has six metal bars, each of the same size. Four of the bars are magnets, one is a bar of unmagnetised steel, and the last is a bar of copper metal. The student places the bars into pairs with a small gap between them, as shown in Fig. 7.1. Select from: attractive force, no force, repulsive force. Each phrase may be used once, more than once, or not at all.
(a)[2]
For every pair of bars in Fig. 7.1, state whether a force is present between the bars. Write your response on the dotted line for each pair.
(b)[1]
Describe what is meant by the term magnetic field.
(c(i))[2]
State one electrically conducting material and one electrically insulating material.
(c(ii))[2]
Explain how current is able to pass through electrical conducting materials.
