[填空题]
A solenoid is carrying ajb uvu2 sp,g*7 y1xkx l3s6cd7 uhoxss(;0h /.bgr.+rhc t -s4 zuf*dq current of $1.2\,A$ in the shown direction.
1.On the diagram above, draw the magnetic field lines produced due to the current in this solenoid.
A proton moving with speed of $5.6\frac10^6\,ms^{−1}$ is moving in the magnetic field of a different solenoid with an angle $35^{\circ}C$ to the field as shown.
2.(1)Determine the direction of the force on this proton due to the magnetic field of the solenoid.
(2)The magnetic field of the solenoid is $4.2\times10^{−3}\,T$. Calculate the magnitude of the magnetic force on the proton. F = $10^{-15}\,N$
(3)State and explain the shape of the path that the proton takes as it travels through the field.
(4)Another proton with the same speed enters the same magnetic field as shown.
Discuss whether it will experience the same force as the proton in part b(ii).
