Question

which object will have the greater density: a pure iron anchor or a pure iron magnet

Explanation:

Step1: Recall density concept

Density is a characteristic property of a substance, defined as mass per unit volume ($
ho=\frac{m}{V}$). It depends on the substance and its state, not on the shape or use - case of the object.

Step2: Analyze materials

Both the pure iron anchor and the pure iron magnet are made of the same substance, pure iron.

Step3: Determine density relationship

Since they are the same substance under the same conditions (assuming no impurities or phase - changes), their densities are equal.

Answer:

They have the same density.
