A magnetic field is produced around the wire 2 of 8 How can the shape of the magnetic field be seen as? A series of concentric circles in a plane, perpendicular to the wire 3 of 8 What does the direction of these field lines depend on? The direction of the current 4 of 8 What does a wire placed in a magnetic field experience? A force 5 of 8 What is this force called? The motor effect 6 of 8 How can the size of the force be increased? Increasing the strength of the magnetic field, Increase the size of the current 7 of 8 How can the direction of the force be reversed? If either the direction of the current or the direction of the magnetic field is reversed 8 of 8
