题目如图1所示,顶角θ=45°的金属导轨MON固定在水平面内,导轨处在方向竖直,磁感应强度为B的匀强磁场中,一根与ON垂直的导体棒在水平外力作用下以恒定速度v0沿导轨MON向右
The problem is shown in Figure 1. The metal rail MON with the vertex angle θ=45° is fixed in the horizontal plane. The rails are in the vertical direction. The magnetic induction intensity is in the uniform magnetic field of B, and the conductor bar perpendicular to ON is in the horizontal force. Under the action of a constant speed v0 along the guide MON to the right
