Please help me answer and explain how to get each answer

1) A proton travels with a velocity of 7 m/s through a magnetic Field of 0.5 Tesla as shown below. a. What is the direction of the magnetic force? b. What is the magnitude of the magnetic force? 2) A lithium Ion LLiit is traveling with a constant velocity v in a magnetic field that is coming out of the page. a. Will it travel clockwise or counterclockwise? b. If you doubled the velocity of the Lithium ion how would the radius change? B-out of page O O O O O O 3) A long, straight, vertical segment of wire traverses a magnetic field of magnitude 2.0 T in the direction shown in the di The length of the wire that lies in the magnetic field is 0.60 m. When the switch is closed, a current of 4.0 A flows thro wire from point P to point Q. switch a) What is the direction of the force on the segment of wire in the magnetic field? b) What is the magnitude of the Magnetic force c) Imagine you wanted to make the segment of wire levitate off the page. What would you need to change in the set-up to make this possible? 5) The radius of a loop of wire is r = 0.3 m. A clockwise current of Is-1.0 A flows in the coil, as shown. A long, straight wire carrying a current Zeiss is located d = 0.4 m from the edge of the coil. The magnetic field at the center of the coil is zero tesla. wire d coil a) What direction of should the current flow through //wwwwwwww to make this true
