Question

7he magnetic field will he stronger if you increase the current you deeease the curient you switch the direction of the current The magnetic field will be stronger if you increase the radius of the loop you decrease the radius of the loop the radius won't affect the field strength the diagram to the righ, indicate the direction

considering the magnetic field in the center of a current carrying loop of wire

Answer 1

magnetic field at the cenre of the loop is given by

$B = \frac{\mu_0 i}{2R}$

1) You increase the current

to increase the magnetic field

2) since magnetic field is stronger if radius will decrease

as it inversely depends on radius
