Magnetic fields do not exist because we cannot see them.
True!
False.
Depends on the day.
Depends on the time.
Increasing the coils around increases the strength of the magnetism affect.
No, it more coils means a weaker magnetism.
It makes no difference.
That is correct, more coils means stronger magnetism.
It increases then decreases.
It decreases then increases.
The Earth has a naturally occurring magnetic field because of the ocean.
True
False
Ocean water has salt which is conductive
Actually, it can only be formed in the clouds
One of Earth’s Magnetic Field purpose is...

Which is not true about magnetic field?
A magnetic object has a field around it.
The field around a magnetic object can be seen using magnetic filings.
Magnetic force in the field increases as you move away from the object.
If a second magnetic object is placed in the field it will experience repulsive or attractive force.
Which is not true about an electromagnetic field?
An electromagnet creates a magnetic field.
An electrical energy source is required to create an electromagnet.
Magnetic objects behave differently in an electromagnetic field than in a magnetic field.
If a magnetic object is placed in the electromagnetic field it will either experience a repulsive or attractive force.
What would happen if you cut a magnet in half?
The material will no longer be magnetic.
One magnet will be the south pole and other the north pole.
Each half of the magnet will have a south and north pole.
Each magneti will be stronger than the original magnet.
