- Homework Statement
- "A long solenoid has a radius of 2.08 cm and 1070 turns per meter. Over a certain time interval the current varies with time according to the expression I = 2.80t, where I is in amperes and t is in seconds. Calculate the electric field 4.54 cm from the axis of the solenoid."

- Relevant Equations
- E=(1/2r)(alpha)R^2(muo)Ioe^-(alpha)t.

The formula we are given is E=(1/2r)(alpha)R^2(muo)Ioe^-(alpha)t.

However, I am struggling to figure out what each of the symbols stands for in the formula...can someone help me out? Like super confused on what alpha is in this case.
