Answer:
1. all electrical appliances has limited capacity of current which can use it and work. When a current passed higher than its capacity then it can fuse or burst so all devices have fuse separately. fuse is a device which has a tiny conductor inside it when high voltage is passed it will breaks and there will not be material to conduct current. So it helps to save appliances from damage
2.a)Magnetic field lines move from north to south and in inside the magnet it moves from south to north.
b)They will not intersect each Other
