Imagine a wire with current [ is directed at an angle 8, shown below. Fp= KT % B out of page Cross-sectional area A W The wire s kecated within in & magnetic field, Using the coardinate system, we see that the magnetic field points in the negative y-direction, or -J"L. Now, we will use the right-hand rule to determine the direction of the farce on the wire from the magnetic field. Start with your fingers in the direction of the current. However, in this case, the current is at an angle. Then, curl your fingers downward In the direction of the magnatic field. As your fingers align with the current and you curl your fingers in the direction of the magnetic field, f, your thumb paints in the direction of the force, Tn this case, the force will be out of the page, or k. = - , Consider a horizontal 25.0 cm long wire running perpendicular to a magnetic field, B = 1.30 Tj. The current is 3.00 A-J, The magnitude of the force on the current is : N. What direction is the force on the wire? ~ i O k O -j 0 None of these are correct. If the wire rotated 90 degrees clockwise, the force on the wire will : * Decrease * |ncrease * Remain the same
