A student sets up the apparatus shown below to investigate how an electromagnet can be used to lift and release small steel nails.

An experimental setup showing a low voltage DC power supply connected via a switch to a coil of insulated copper wire wrapped around a cylindrical metal core. Magnetised by the current, the core is suspended above a beaker containing several small steel nails.

The student chooses to use soft iron as the core of the electromagnet instead of steel.

Give two reasons why soft iron is more suitable than steel for the core of this electromagnet.
