What is the vector diagram of a transformer?

If in a diagram, the velocity vector points up and the electric field vector points towards the right, then...?

  • what direction would the magnetic field vector point? in or out of the page?

  • Answer:

    Is this about a charged particle being undeflected (so called 'crossed fields')? If so, you need to know the sign of the charge. Assuming it is positive... The electric force on the charge will act to the right. So the magnetic force must act to the left. Using Fleming's left hand rule (see link), the magnetic field points into the page (away from you you). If the charge is negative the magnetic field points out of the page (towards you).

Hello Zora :3, you mean the magnetic field needed to keep the charged particle remain in its path without deviation. Am I right? If so then the magnetic field has to be into the page. Applying Fleming's left hand rule, the charged particle would get deviated towards left. So the right side deflection due to electric field will be nullified by the left side deflection due to magnetic field.

into the page.. see V || E x B ( cross product of electric field and magnetic field vector).. this gives the required result
