Identify the objects around which a magnetic field is created by placing a tick mark (✓) next them.
Fig. 1.1 shows the magnetic field lines and the plane of the magnetic field.
Fig 1.1
Sketch on the diagram the object creating the magnetic field and the direction of the current flowing.
The magnetic field lines surrounding a different object are shown in Fig. 1.2.
Fig. 1.2
State the name of the object and the the direction of the current passing through it.
Fig. 1.3 shows the current passing through a single circular coil.
Fig. 1.3
Sketch the field lines around the coil.
