The shape of the magnetic field can be seen as a series of concentric circles in a plane, perpendicular to the wire. The direction of these field lines depends on the direction of the current. The strength of the magnetic field depends on the current through the wire and the distance from the wire. 0.5 Describe how the magnetic effect of a current can be demonstrated. Use the ‘right hand thumb rule’ to draw the magnetic field pattern of a wire carrying an electric current. Demonstrate what happens when a foil strip with a current flowing through it is placed in a strong magnetic field. What happens if the direction of the current is reversed? Try to demonstrate the shape of the magnetic field by placing a wire through a piece of card with iron filings sprinkled near it. Apply a current through the wire.
