the way in which the positive & negative terminals on the battery or power supply are attached to the electromagnet.
switching the leads from the positive terminal to the negative one, and the negative one to the positive terminal should reverse the polarity of your electromagnet.

The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
The what of an electromagnet is determined by the direction of current flow?
The polarity of an electromagnet is determined by the direction of current flow. When current flows one way, the magnetic field is oriented in one direction, and when it flows the other way, the magnetic field is oriented in the opposite direction.
How can a polarity of an electromagnet be determined if the direction of current flow is known?
The polarity of an electromagnet can be determined by the right-hand rule. If the direction of the current flow is known, curl your right hand fingers in the direction of the current flow. Your thumb points in the direction of the north pole of the electromagnet.
How is the polarity of a resistor determined?
Resistors do not have a polarity. BY DEFINITION, a resistor is a device that follows Ohms law, and does so regardless of the polarity in which it is inserted into a circuit. Manufacturers of resistors do all they can to make their resistors follow that definition. One way to make a resistor have no polarity is to build it so that it is mechnically symmetrical about its two leads. Doing so will ensure that it will also be electrically symmetrical, and thus non-polarized
How can the polarity of an electromagnet be determined if the direction of current flow is unknown?
The polarity of an electromagnet can be determined using the right-hand rule: wrap your fingers around the coil in the direction of the current flow (conventional current flow is from positive to negative), with your thumb pointing in the direction of the magnetic field. The side of the coil where your thumb points is the north pole of the electromagnet.
The polarity of an electromagnet is determined by what?
The polarity of an electromagnet is determined by the direction of the electric current flowing through the wire coil. Reversing the direction of the current will change the polarity of the electromagnet.
What are some properties of water that are determined by its polarity?

What is the relationship between bond polarity and molecular polarity?
The relationship between bond polarity and molecular polarity is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. If a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar overall.
How can the polarity of a magnet be determined?
Use a compass. It will always point to a magnet's south pole.
The what of an electromagnet is determined by the direction of current flow?
The polarity of an electromagnet is determined by the direction of current flow. When current flows one way, the magnetic field is oriented in one direction, and when it flows the other way, the magnetic field is oriented in the opposite direction.
What is the relationship between bond polarity and molecular polarity in chemical compounds?
The relationship between bond polarity and molecular polarity in chemical compounds is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. Conversely, if a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar.
How can a polarity of an electromagnet be determined if the direction of current flow is known?
The polarity of an electromagnet can be determined by the right-hand rule. If the direction of the current flow is known, curl your right hand fingers in the direction of the current flow. Your thumb points in the direction of the north pole of the electromagnet.
What is the relationship between molecular polarity and bond polarity?
Molecular polarity is determined by the overall arrangement of polar bonds within a molecule. If a molecule has polar bonds that are arranged symmetrically, the molecule is nonpolar. However, if the polar bonds are arranged asymmetrically, the molecule is polar. Therefore, the relationship between molecular polarity and bond polarity is that the presence and arrangement of polar bonds within a molecule determine its overall polarity.
How can the degree of polarity be predicted?
The degree of polarity in a molecule can be predicted by considering the electronegativity difference between the atoms in the molecule. The larger the difference in electronegativity, the more polar the molecule will be. Additionally, the molecular geometry and symmetry can also influence the degree of polarity in a molecule.
How is the polarity of a resistor determined?
Resistors do not have a polarity. BY DEFINITION, a resistor is a device that follows Ohms law, and does so regardless of the polarity in which it is inserted into a circuit.

One way to make a resistor have no polarity is to build it so that it is mechnically symmetrical about its two leads. Doing so will ensure that it will also be electrically symmetrical, and thus non-polarized
How are the plus and minus voltage signs determined for resistors?
Resistors have no polarity. The voltage across a resistor is determined by the direction of current flowing through that resistor (and vice versa).
