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 strength of the magnetic fields field depends on: The size of the current The distance from the long straight conductor (such as a wire) A larger current will produce a larger magnetic field and vice versa The greater the distance from the conductor, the weaker the magnetic field and vice versa

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. hu jura partyWebMar 21, 2024 · Magnet BBC Bitesize science Nehal Anbar 4.17K subscribers Subscribe Share Save 25K views 2 years ago Magnet ,ks2 Show more Show more Try YouTube Kids Learn more … hu juntasWebFeb 15, 2024 · electromagnetism, science of charge and of the forces and fields associated with charge.
