Consider a 10cm long protion of a straight wire carrying a current of 10 A placed in a magnetic field of 0.1 T making an angle of `53^@` with the wire. What magnetic force does the wire experience?

Explanation

Required force ` vecF = i vecL xx vecB `
` = ` |vecF| = ilB xx B sim 53 `
`= 10 xx 10 xx 10^(-2) xx 0.1 xx 0.798 `
(toward _|__r to vecl and vec B)`
= 0.08 N toward _|_r , to vecI and vecB
