STATEMENT: A homogeneous metal bar AC, of ​​mass m and length L, is fully immersed in a region where a uniform magnetic field of intensity B acts, directed perpendicularly into the page. The bar is supported at one end by an ideal insulating wire that forms an angle θ with the vertical, and at the other end, it rests on a rubber support whose coefficient of static friction between the surfaces is μ, as shown in the following figure.
