I am working on a project and I need to control 16 electromagnets.
  • Input Voltage: 12V DC
  • Current: 0.33A
  • Power Consumption: 4W
I need to turn them on and off very rapidly and switch their polarity. I'm very much a newbie and was looking for the best way to accomplish this.

Welcome to the forum.

You need to define what you want better.
Are they all going to be switched together or are they to run in a sequence.
What is very rapidly? An elecromagnet is inductive and switching it rapidly is difficult.
What will be the method of deciding what should be done?

Thanks.

Yes they will be fired in a series. What type of speed can they be fired in at a max?

Aren't the magnets in a motor turned on and off and reversed polarity at a high rate of speed?

It all depends on what the electromagnets are designed to do.
What is the purpose of reversing the polarity?
If this is similar to a solenoid or relay, the armature will stay retained.
A P.M. has to be introduced.

Sorry I didn't see the reply. I want to take advantage of both properties of electromagnetism, the pushing and pulling in a new motor I am working on. No actuating involved.
