Question

Which of the following material has its magnetic susceptibility x in the range 0 < x < ε, where ε is positive and small?

Options

• Aluminium

• Water

• Gadolinium

• Bismuth

Answer 1

Aluminium

Explanation:

The susceptibility of ferromagnetic materials is considerably high. Paramagnetic substances have a low and positive susceptibility to magnetic fields. Paramagnetism is a property of aluminum. A diamagnetic substance is water and bismuth. When it is at room temperature, gadolinium is believed to be paramagnetic despite its ferromagnetic properties.
