1. A proton is moving at an angle of 80° to a uniform magnetic field. What is the relationship between the direction of the force on the proton and the direction of the magnetic field? * (1 Point) parallel to the magnetic field at an angle of 10° to the magnetic field at an angle of 80° to the magnetic field at an angle of 180° to the magnetic field perpendicular to the magnetic field 2. An electron is moving...
A magnetic field in the center of a solenoid has a magnitude of 3.5 x 10-2 T was generated by an unknown current. The length of the solenoid is 1.5 m and it has 950 turns of wiring. Determine the current.
A proton and an electron traveling at the same speed enter a uniform magnetic field. The velocity vector of each particle is perpendicular to the magnetic field. What will be ratio of the radii of their circular orbits (rproton/relectron)? O 5.5E-4 O 0.5 O 1.0 O 1800 O 3600 A horizontal length of current-carrying wire is suspended from two identical flexible leads that are under tension due to the weight of the wire. The wire is oriented at right angles...
For many technical applications, it is desirable to have a uniform magnetic field, i.e. a field with the same strength and direction at every point in a certain region of space. As you discovered in the last checkpoint, this can be achieved with a solenoid, which is constructed by "stacking" many loops of wire, each with the same current. The superposition of the magnetic fields of the single loops creates a strong, nearly uniform field inside the solenoid, whereas the...
A charge particle enters a uniform magnetic field and follows the circular path shown in the drawing. f (a) Is the particle positively or negatively charged? O positive O negative O electrically neutral Why? This answer has not been graded yet (b) The particle's speed is 110 m/s, the magnitude of the magnetic field is 0.46 T, and the radius of the path is 960 m. Determine the mass of the particle, given that its charge has a magnitude of...
The magnetic field of a proton is relatively close to that of a circular current loop 0.650 times 10^-15 m in radius carrying 1.05 times 10^4 A. An MRI machine is required to be able to manipulate these fields. To see why an MRI utilizes iron to increase the magnetic field generated by a coil, calculate the current needed in a 400 loop-per-meter circular coil 0.660 m in radius to generate a 1.20 T field (typical of an MRI instrument)...
