Which that the following influences the emf produced in a cable loop the is rotating in a magnetic field?
You are watching: Which of the following best describes magnetic field lines?
First, magnetic ar lines, like electric field lines, have the right to never cross. Also, unlike electrical field lines, magnetic ar lines are continuous—they do not have starting or ending points. Next, the pressure experienced by a charge in a magnetic ar depends on the charge\"s velocity direction, not just the magnetic field. Therefore the just remaining selection is that magnetic ar lines display both the family member strength and direction of the field.
We usage the formula for force on a cable in a magnetic field:
A scientist build a bit accelerator. I beg your pardon of the adhering to would not help the scientist increase the rate of a particle in the accelerator?
A charged bit in a fragment accelerator moves in uniform circular motion. The equation for centripetal force caused by uniform circular movement is:
The equation because that magnetic pressure is:
Set the equations equal to every other, and also solve because that velocity.

The only answer choice that does not correspond to rise in velocity is raising the massive of the corpuscle in the accelerator.
