You are presented with the question "What happens when a wire is moved across a magnetic field?" and the following answer choices: 
- unidirectional
 - the wire heats up
 - deoxyribonucleic acid
 - permineralization
 - electromagnetic energy
 - activation energy
 - An object is seen
 - direct energy

Now knowing that electrical current running through a wire causes that wire to heat up and when the wire is moved across the magnetic field, it creates an electric current, choose the best answer.


 

  the wire heats up
