Reverse the current. :D
If the direction of the current in an electromagnet is reversed, the direction of the magnetic field surrounding the electromagnet will also reverse. This change in direction will affect the polarity of the electromagnet, causing its north and south poles to switch.
The direction of the magnetic field around the electric current also reverses when the direction of the current is reversed. This is determined by the right-hand rule, where the direction of the magnetic field is perpendicular to the direction of the current flow.
True. When the direction of the current is reversed, the direction of the magnetic field also reverses. This is in accordance with the right-hand rule for determining the direction of the magnetic field around a current-carrying conductor.
When the direction of the current in a wire is reversed in a magnetic field, the direction of the force acting on the wire also reverses. This causes the wire to move in the opposite direction within the magnetic field.
Yes, the Earth's magnetic field has periodically reversed its direction throughout history. These reversals are known as geomagnetic reversals and have occurred many times over the past few million years.

The idea is that the magnetic field of the device reacts with the external magnetic field. If the current is reversed, the magnetic field would also be reversed, and the reading would be the opposite.
Yes. If a current is reversed, the magnetic field is reversed as well.

When the electric current is reversed on an electromagnet, the direction of the magnetic field is also reversed. This means that the north and south poles of the electromagnet switch places. This change in polarity can have various effects depending on the application, such as reversing the direction of motion in a motor or changing the direction of attraction or repulsion in a magnetic system.
The direction of the force that drives the machine is determined by the relative directions of the field and the armature current. By reversing the direction of both field and the armature current, the direction of the resulting force stays the same; you have to reverse the direction of one or the other; not both! Prove it for yourself, by applying Fleming's Left-Hand Rule (for conventional current flow); reverse the direction of both your first finger (field) and your second finger (armature current), and you thumb (direction of motion) will end up pointing in the same direction!

DC shunt motor can be reversed by changing the polarity of either the armature coil or the field coil.
Yes, when the flow of electricity in a wire near a compass needle is reversed, the magnetic field generated by the current also changes direction. This change in magnetic field influences the orientation of the compass needle, causing it to change direction accordingly.
