How can I calculate the magnetic field using electromagnetic induction?

Click For Summary
SUMMARY

The discussion focuses on calculating the magnetic field (B) using electromagnetic induction principles. The relevant equation provided is missing an angle, which should be set to π/2 for minimum magnetic field calculations. Participants emphasize the importance of knowing the current (I), length (L), and force (F) to derive the magnetic field accurately. The conversation highlights the necessity of applying these parameters correctly to achieve the desired results.

PREREQUISITES
  • Understanding of electromagnetic induction principles
  • Familiarity with the equation relating current (I), length (L), and force (F)
  • Knowledge of trigonometric functions, specifically the angle π/2
  • Basic physics concepts related to magnetic fields
NEXT STEPS

Homework Statement
A .76 meter long wire runs horizontally and carries a current of 28A (left to right). What would be the magnitude and direction of the minimum magnetic field to suspend the wire in mid air if the wire has a mass of 46.6 g/m?
Relevant Equations
I think its F=ILBsin
gotta be honest I am really struggling

Hello mountain, ##\qquad## :welcome: ##\qquad## !

Unfortunately the PF guidelines require an attempt at solution before we are allowed to assist.

Your relevant equation is good (misses an angle at the end, but for minimum B an angle of ##\pi/2## does the trick).
So what is the problem ? You have I, L and you can calculate F. Then B follows !
