Magnetic Fields
Consider a charged particle moving in a magnetic field with a constant velocity of \(20\hat{i} \text{ km/s},\) in a direction perpendicular to the magnetic field. The mass and charge of the particle is \(13\text{ g}\) and \(75\,\mu\text{C},\) respectively. If the free-fall acceleration in the magnetic field region is \(-9.8\hat{j} \text{ m/s}^2,\) what is the appropriate magnetic field?
A uniform magnetic field \(\vec{B}\) of magnitude \(1.5\text{ mT}\) is directed vertically upward. If a proton with kinetic energy \(5.5\text{ MeV}\) enters the chamber horizontally, what is the approximate magnetic deflecting force acting on the proton as it enters the magnetic field?
The proton mass is \(1.67 \times 10^{-27} \text{ kg}\) and \(eV=1.60 \times 10^{-19} \text{ J}.\) (Neglect Earth's magnetic field.)
The value of the elementary charge is \(e=1.60 \times 10^{-19} \text{ C}.\)
A proton is traveling in a magnetic field of \(2.30 \text{ mT}\) with the angle of \(30.0^\circ\) with respect to the direction of the magnetic field. If the proton experiences a magnetic force of \(6.80 \times 10^{-17} \text{ N},\) what is the approximate kinetic energy of the proton?
The proton mass is \(1.67 \times 10^{-27} \text{ kg}\) and the value of the elementary charge is \(e=1.60 \times 10^{-19} \text{ C}.\)
