This question is ambiguous. We don't know what you want to break the magnetic field of.
However, in general, strong vibrations, heat, and an alternating current field are several ways to reduce or destroy magnetism.

The properties and interactions of magnets are called magnetism. Magnetism is the force of attraction or repulsion that acts between magnets, as well as between magnets and materials that can be magnetized, such as iron and steel. Magnetism is a fundamental force in nature that plays a role in various everyday applications, from compasses to electric motors.
Yes, magnets can lose their magnetism over time due to factors such as exposure to heat, physical damage, or demagnetizing fields.
Yes, because electromagnets can lose their magnetism.
