Suppose I have a circular loop of wire with radius R. I run a current I through the loop and measure a magnetic field B at the center of the wire. If I double the radius of the wire and triple the current in the wire, what is the new magnetic field at the center of the wire

Explanation:

The magnetic field at the center of the wire is given by :

Here,

I is current flowing throgh the loop

r is the radius of loop

If the radius of the wire is doubled and the current is tripled, then new magnetic field is given by :

So, the new value of magnetic field gets 3/2th of the initial magnetic field.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
