The magnetic field is magn perpendicular to the axis of the wire and to the direction of motion. (Figure 1) What is the strength of the magnetic field Express your answer using two significant figures. Figure 1 of1 10 cm Submit My Answers Give Up Part B What is the direction of the magnetic fiel d? Into the screen Out of the screern 5.0 m/s Submit My Answers Give Up rovi Continue force act on an.B) If the radius of the proton's circular path in the magnetic field is 7.4 cm , what is the radius of If the loop is located in a magnetic field given by B = 0 1:08 n'US

Explanation / Answer

Part A )    Motional induced emf = B * L * v

     => B = E/Lv

               = 0.05/(0.1 * 5)

               =   0.1 T              -------------> magnetic field

Part B)    direction of magnetic field = into the screen
