Statement A: Soft magnetic material is used in making electromagnets - This statement is true. Soft magnetic materials, such as iron, nickel, and cobalt, are commonly used in the construction of electromagnets. These materials have high magnetic permeability and low coercive field, which allows them to be easily magnetized and demagnetized.
Statement R: Soft magnetic materials have a high coercive field - This statement is false. In fact, soft magnetic materials have a low coercive field. Coercive field, also known as coercivity, is the measure of a material's resistance to becoming demagnetized. Soft magnetic materials are designed to have low coercive field, which means they can be easily magnetized and demagnetized with relatively low magnetic fields. This property makes them suitable for applications like electromagnets where rapid magnetization and demagnetization are required.
Therefore, while Statement A is true, Statement R is false. The coercive field of soft magnetic materials is low, not high. Hence, the correct answer is (C) A is true but R is false.
