newton 1st law: w no external force, a body will stay at rest or in constant uniform motion.
a motor raises the car up the tower. cuz it moves w/ constant vel, there is no external force: the motor force is the same n in opposity direction as the gravity force on car.

Answer:
Explanation:
1. A solenoid is a coil which has many turns. When current flows through a solenoid, it behaves as an electromagnet. This behavior is due to the magnetic effect of an electric current thereby causing one end of the solenoid to behave as a north pole, while the other end as a south pole.The external influence of the earth's magnetism constrains the solenoid to come to rest in a N-S position just like a bar magnet.
2. The magnetic compass can be used to trace the alignments or patterns of the magnetic field around a current carrying wire. When current flows in a wire, it induces magnetic field around it. If the value of current is increased, the strength of the magnetic field would increase and vice versa. This shows that current is proportional to the strength of the magnetic field produced around the wire. Thus this causes a deflection of the compass appropriately, as the deflection of the compass is proportional to the strength of the field.
