Question

Obtain an expression for the magnetic force on a straight wire carrying a current and placed in an uniform magnetic field?​

Answer 1

$\Large{\underline{\underline{\bf{Answer:-}}}}$

F=(nqAvd)lBsinθ. is the equation for magnetic force on a length l of wire carrying a current I in a uniform magnetic field B, as shown in Figure 22.7. 2. If we divide both sides of this expression by l, we find that the magnetic force per unit length of wire in a uniform field is =IBsinθ.

Answer 2

Answer:

F=(n Avd)IBsino. is the equation for magnetic force on a length I of wire carrying a current I in a uniform magnetic field B, as shown in Figure 22.7. 2. If we divide both sides of this expression by I, we find that the magnetic force per unit length of wire in a uniform field is =IBsine.
