Problem 43 Easy Difficulty

Find the current through a loop needed to create a maximum torque of 9.00 $\mathrm{N} \cdot \mathrm{m} .$ The loop has 50 square turns that are 15.0 $\mathrm{cm}$ on a side and is in a uniform $0.800-\mathrm{T}$ magnetic field.

Answer

The current in the loop is 11.3 $\mathrm{A}$

Video Transcript

find the current in a loop, which creates a maximum torque off nine meter. And but Luke has 50 square turns and each turn as a side off 15 centimeters and the unit for the uniform magnetic figure. These zero point dates slot, so maximum torque is nine. You turn me turn and in there of turns signed off square, which is your point picking meters, and the uniform magnetic field is 0.8 and we're looking for current, you know. So the formula for a talk general formula to find the talk is number of turns while you play by occurring in a loop. While complains I magnetic fields the area off each individual individual Luke and Science center angle between on the magnetic field and their loops. Normal victor and well, we know where if we know that these talking maximum, the turkey's a maximum while you value event science and becomes one. And if we know that this is the case, then they lay just said, saying That is one, and from here we can find the current, which would be talk directed by number returns, the magnetic field field and the area off each individual individual, which is a boxing which is exactly 10 um, purse
