The magnet dimensions are about 6x6x12mm. If a 12 mm long solenoid were constructed with 100 turns - each turn having a 36mm^2 cross sectional area, how much current would it have to carry to have the dipole strength of your magnet? This calculation will let you see how you could use a solenoid to produce a magnetic field equal to that of your bar magnet

e) none of the above answers are correct

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
