Answer the following question given this paragraph: 

Electricity and magnetism are inextricably linked. Under certain conditions, electric current causes a magnetic field. Under other conditions, a magnetic field can cause an electric current. A moving charged particle creates a magnetic field around it. Additionally, when a moving charged particle moves through a different magnetic field, the two magnetic fields will interact. The result is a force exerted on the moving charged particle.


Q: Under certain conditions, electric current causes what type of field?

 Choices:

- light

- kinetic

- seismic

- magnetic

A:
magnetic
