Wire 1 is now removed and Wire 2 is exposed to a magnetic field of strength 73 mT such that the magnetic field lines make an angle to the wire as shown in Figure Q3c The current in Wire 2 has the same magnitude as in b and flows downwards Wire 2 experiences a magnetic force of magnitude 859 uN c Determine the direction of this magnetic force stating the name of the rule which you use to determine this and calculate Figure Q3c Orientation of magnetic field lines around Wire 2 The current supplied to Wire 2 is now switched off It is placed in a region of magnetic field strength 415 mT where the wire can be moved at a constant speed v in the horizontal plane either to the left or to the right as shown in Figure Q4d During this process an emf of 0 10 V is induced across the ends of the wire and the top end of the wire acquires a positive charge d Calculate the velocity of the wire including a direction and state the rule used to determine this direction B H 3 3
