Describe how turning off the electric current in an industrial electromagnet affects its magnetic field

The magnetic field turns off.

Explanation:

An electromagnet is coiled wire carrying current through it. The current carrying loop produces magnetic field. The strength of the magnetic field varies with the amount of current and number of turns in the wire.

The industrial magnetic field has ferromagnetic material like iron placed at the center. This increases the strength of the magnetic field.

When the electric current is switched off, the magnetic field produced due to coil turns off.

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.
