are electrical and magnetic fields at right angles or opposite to eachother?

^^
thanks!

Are electric and magnetic fields at right angles?

yes and no

Are electric and magnetic fields opposite to each other?

yes and no (no physical laws tell me they (electric and magnetic fields) cannot be opposite)

Not really sure what you are trying to ask, so my answer is also.... :smile:

What is the context of your question?

sorry for not being specific- I was doing this past paper question below:

Explain the use of a uniform magnetic field and a uniform electric field for the selection of the velocity of charged particles. You may draw a diagram if you wish.

The markscheme said: electric and magnetic fields normal to each other B1 velocity of particle normal to both fields B1 forces (on particle) due to fields are in opposite directions B1 forces are equal for particles with a particular speed/for a selected speed/for speed given by v = E(q) /  B(q)

I thought electric and magnetic forces were opposite to eachother, not perpendicular?

Based on the setup where electric and magnetic fields are normal to each other, the electric and magnetic forces are opposite to each other.

You may want to review the concepts here or using this video:


And tried out this question to test your understanding.
