Web1. An electromagnet on a crane is used in a scrapyard because: It can be turned on and off It can't be turned on and off It is stronger than a permanent magnet It is weaker than a permanent magnet 2. If the current direction through the wire is reversed, the direction of the magnetic field: Is also reversed Stays in the same direction WebThe Earth's gravitational field strength at, or close to, the surface is 10 N/kg. This means that for each kilogram of mass, an object will experience 10 N of force. Where there is a weaker gravitational field, the weight of an object is smaller. For example, the gravitational field strength of the Moon is 1.6 N/kg.
