A wire carries a 4.0-A current along the +y-axis through a magnetic field

A loop of radius r = 6.0 cm is placed parallel to the xy-plane in a uniform magnetic field in the +z direction. The resistance of the loop is 4 Ω. Starting at t=0, the magnitude of the field increases uniformly from zero to 4.2 T in 0.33 seconds. What is the induced current produced in the loop during that time with the correct sign?

A wire carries a 6.0-A current along the +y-axis through a magnetic field

A proton moving in the direction of the +y-axis enters a magnetic field. If the proton experiences a magnetic deflection in the +z direction, the direction of the magnetic field in this region points in the direction of the

A 12.0-m long conducting wire is formed into a square and placed in the x-y plane. A uniform magnetic field is oriented 60.0° from the normal to the surface of the square with a strength of 12.0 T. What is the magnetic flux through the square? Hint: What are the side lengths of a square with a perimeter of 12.0 m?

A point charge Q moves on the y-axis in the positive direction with a speed of 268 m/s. A point P is on the z-axis at z = 0.03 m. The magnetic field produced at the point P, as the charge moves through the origin, is equal to 0.50 μT
