ammeter
A weather vane is an instrument that measures wind direction by pointing in the direction from which the wind is blowing. It typically consists of a rotating arrow attached to a fixed base, allowing it to align itself with the wind.
An ammeter is the instrument used to measure current in an electric circuit. It is connected in series in the circuit and provides a reading of the amount of electric current flowing through it.
An instrument that measures heat and cold is called a thermometer.
A compass is an instrument that shows direction by pointing towards the magnetic north pole.
The direction of the magnetic force on the current in (a) is perpendicular to both the direction of the current and the direction of the magnetic field.
An anemometer is the instrument that measures wind direction using a wind vane.
An ammeter. It measures the electrical current output.
An instrument that measures electric current in amperes.

This could describe a magnetic compass.
A thermometer is sufficient.

A compass measures direction by aligning itself with the Earth's magnetic field, indicating the cardinal directions (north, south, east, west).
An ammeter is the instrument that measures electric current in a circuit. It is connected in series to the circuit to measure the flow of current through it.
An anemometer measures wind speed. On the other hand, a wind vein is used to determine the direction of the wind.
It measures the current.
