Homework Statement
A magnetic field is uniform throughout a region of space, but increases from 0 to 0.14 T in 2.4 s. A circular coil (of diameter 19 cm) is placed in a fixed orientation in this region such as to receive maximum flux. It takes 4171.91 turns to generate an emf of 6.9 V
What inherent property of the coil determines the degree to which it is able to fight the flux change, per Lenz's Law?a) curent
b) EMF
c) Resistance
d) induced magnetic field
The Attempt at a Solution
I'm leaning toward saying that it's a) current. I know I dont' compeltley understand this yet, but I see nothing about inherent properties of coils in my book. All I've gleaned from my reading is that the current will always flow in the direction that opposes the change that caused it.
Can anyone confirm that I'm on the right track?
