You are requested to post each query seperately.
It is advisable to connect all the appliances in the circuit with a fuse of appropiate current carrying capacity for their safety. A fuse with a rating higher than the defined one may allow current to pass which is higher than the maximum current that can be taken by the appliance and thus the appliance may gat overheated and damaged. There may even be chances of short-circuit.
Ideally, the fuse provided with an electrical appliance to protect it against electric faults, must be of current rating slightly higher than the maximum current that can be taken by the appliance.
If the direction of current flowing through the solenoid is reversed, the direction of magnetic field due to solenoid is also reversed.
We hope this clarifies your doubt.
