The Biggest Mistake Students Make With Electromagnetism

Are you consistently losing points on Electromagnetism because of forgetting the right-hand rule applies to positive charges? If so, you're making the exact same error as 80% of your class.

Did you make this error?

• The Trap: forgetting the right-hand rule applies to positive charges
• The Proof: Read this scenario: If an electron moves through a magnetic field, you must use your right hand to find the force, and then FLIP the direction because it's a negative charge.

If your logic doesn't match the proof above, you've fallen for the trap. Erase it and start over.
