magnetic field

• the space around a magnet in which magnetic forces can act on objects

• to separate or set apart

• one of the two opposite ends of a magnet

• to provide evidence that goes against a claim

In an electromagnet, coils of wire are wrapped around a magnetic object to generate a magnetic field. What the is relationship between number of coils and the strength of the magnetic field?

• The more coils an electromagntic has, the stronger the magnetic field

• The more coils an electromagntic has, the weaker the magnetic field

• The larger the metal object, the stronger the magnetic field is

• There is no relationship between number of coils and the strength of a magnetic field
