How do you find B?How do you find the mass? (If possible)

Lorent 3 F = 4VB Presentation: mew ~ F = i l'Bj For each value of current through the solenoid coil, the corresponding magnetic field B can mac's site FB be calculated from the force on the current element using: B = F/iloopL F=mg where F = Wstring = mstringg and iloop is the current in the loop element. zero : 3,58 A icoil F iloop B I mass solenoid 3.0 A 1) 5.5 8 cm 1 0.5 length average B.
