Look at Lec 15 slide #2 to answer this question. The question has an electron moving in a circle inside a solenoid. The question is asking you to calculated the magnetic field generated by the solenoid is part (a). Can you use the equation for magnetic field generated by a solenoid ( ) to solve part (a)? Note that the current is not given here. Choose your answer from below and fill in the gap.

You are designing a new solenoid and experimenting with material for each turn. The particular turn you are working with is a circular loop of radius 4.00 cm that carries a current of 20.0 A. Calculate the magnetic field B at the center of the loop.

B = T Consider the coordinate system in the figure. If the circular loop lies in the xy plane and if the current flows clockwise around the loop, which direction does the magnetic field point inside the loop? negative y positive z positive x negative z If the radius is decreased, what will happen to the magnetic field? increase decrease stay the same none of these
