At which angle does some magnetic force reach the conductor?

The angle at which some magnetic force is exerted on a conductor can be understood through the principles of electromagnetism and the relationship between magnetic fields and electric currents. When a conductor, such as a wire, carrying an electric current is placed within a magnetic field, it experiences a force that can be described by the Lorentz force law. This force is maximized when the angle between the direction of the current and the magnetic field is 90 degrees.

However, in terms of effective magnetic force contribution, an angle of 45 degrees allows for an effective interaction between the current and the magnetic field. This angle represents a balance where the sine of the angle gives a non-zero value, meaning that the magnetic force does act on the conductor even though it is not at the maximum potential force. Thus, at 45 degrees, you do indeed have some magnetic force that is acting on the conductor, resulting in significant motion or force, but not at the highest possible level that would occur at 90 degrees.

In summary, the 45-degree angle is noted because it represents an angle where the magnetic force acting on a current-carrying conductor is present, demonstrating the principles of vector components in magnetic interactions.
