A magnetic field vector B is now imposed. springs if the potential voltage is 19 V, the conductor resistance is 15 Ω, the length is 0 . 6 m, the spring constant is 3 . 1 N / m, the conductor mass is 1 . 1 kg, and the acceleration due to gravity is 9 . 8 m / s 2 ? Which direction should the magnetic field point to have the most effect in raising or lowering the heavy conductor? 1.

Rearranging and using I = V R , we get B = m g R ℓ V = (1 . 1 kg) (9 . 8 m / s 2 ) (15 Ω) (0 . 6 m) (19 V) = 14 . 1842 T . 014 (part 1 of 2) 10.0 points The gravitational force on loop is downward. A rectangular loop with dimensions (hor- izontal = 0 . 23 m) × (vertical= 0 . 529 m), is suspended by a string, and the lower hori- zontal section of the loop is immersed in a magnetic field.
