Questions from David Sang and Graham Jones Solutions for Chapter: Magnetic Fields and Electromagnetism, Exercise 2: Questions with Hints & Solutions
Sketch the magnetic field pattern around a long straight wire carrying an electric current. Now, alongside this first sketch, draw a second sketch to show the field pattern if the current flowing is doubled and its direction reversed. How does the pattern show that the field is stronger nearer the wire?
Sketch the diagram in Figure, and label the north and south poles of the electromagnet. Show on your sketch the direction of the magnetic field (as shown by the needle of a plotting compass) at each of the positions A, B, C and D.
A current-carrying solenoid.
State which of the pairs of electromagnets shown in Figure attract one another, and which one repel.
