You hold a wire coil so that the plane of the coil is perpendicular to a magnetic field B ⃗ B→ . Part A If the magnitude of B ⃗ B→ increases while its direction remains unchanged, how will the magnetic flux through the coil change?1. The flux is unchanged because the position of the coil with respect to B is unchanged l 2. The flux increases because the magnitude of B increases 3. The flux decreases because the magnitude of B increases 4. The flux is unchanged because the surface area of the co is unchanged
