1. The problem statement, all variables and given/known data A solenoid lies horizontally with a current balance WXYZ balanced in the solenoid core. Sides WX and ZY are 7.1 cm and side XY is 1.9cm. A current of 6.0A flows through the conductor of the balance. If a 17.6g mass is necessary to balance the current balance what is the magnetic field strength of the solenoid - ANSWER - 1.51T 2. Relevant equations Fm=Fg BIL=mg 3. The attempt at a solution i attempted to do them seperately. b= mg/IL that is literally all i can get from this perphaps if i was given a diagram it would help. Ive tried substituing l as 7,1 and 1.9, adding the two lengths and subtracting them didnt work anyone know how to do this?
