Good afternoon, Question: Say I have an electromagnet at a 45 degree incline from an electron beam. This electromagnet is exerting 0.75 Tesla on the beam. How can I calculate the vector that the electromagnet will exert on a particle? Note, this is for my own curiosity, not for any homework assignment- Therefore, feel free to make up numbers if needed... I hope I explained well enough, if not, check out the attached image~ Thank you in advance!
