The given figure shows the current passing through the straight conductor XY.
  1. (i)Copy the diagram and draw the magnetic field lines when current flows from conductor X to Y.
  2. (ii)Name and state the rule used in determining the direction of the magnetic field lines in the situation given above.
  3. (iii)State Fleming’s left hand rule. Using this rule, determine the direction of force applied on an electron entering a uniform magnetic field as shown in the figure.
Q X Y Variable resistance A - + + - K
Straight conductor XY passing through a cardboard sheet Q, in a circuit with a variable resistance, an ammeter, a battery of two cells and a key.
Magnetic field e
