Does a proton have a magnetic field?
Protons and neutrons, both nucleons, comprise the nucleus of an atom, and both nucleons act as small magnets whose strength is measured by their magnetic moments. The magnitude of the proton’s magnetic moment indicates that the proton is not an elementary particle.
Why is the trajectory of the positively charged particle curving down to the bottom of the screen when moving in the magnetic field?
Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The particle continues to follow this curved path until it forms a complete circle.
Why does the path of the charged particle Bend?
The path of the charged particle bends because the particle is repelled by the negatively charged plate and attracted to the positively charged plate. The greater the magnitude of the charges, the greater the electrostatic repulsion or attraction. As the charge on the plates is increased, the bending will increase.
How does magnetic field do no work?
Magnetic fields do no work by definition; since the force due to a magnetic field is orthogonally directed to the motion of a particle, it can only change the direction of motion, but not change the magnitude of the motion.
Does magnetic field do work why?
The statement that magnetic fields don’t do any work only applies to point-like pure electric charges. In terms of formulae, the magnetic force on a charge is q→v×→B which is identically perpendicular to →v and that’s why it does no work.
What makes a magnetic field stronger?
You can make an electromagnet stronger by doing these things: wrapping the coil around a piece of iron (such as an iron nail) adding more turns to the coil.
Why electric field inside a cavity is zero?
If instead the conductor had an interior cavity, the charges would again distribute themselves on the outer surface in order to eliminate the electric field on the inside material of the conductor. (Free electrons cannot move in equilibrium.)
Why there is no charge inside the conductor?
Due to a large number of electrons, the force of repulsion acting in between them is also very high. Hence in order to minimize the repulsion between electrons, the electrons move to the surface of the conductor. Hence we can say that the net charge inside the conductor is zero.
Why is charge always on the outer surface of the conductor?
The electric field inside the conductor is zero. In case of conductors, this electric field is always equal to that of the external electric field and hence the external field is neutralized. Hence all the charges move as far away as possible, i.e. on the surface of the conductor.
