In the modern world, people use electricity at an immense scale, although few comprehend that magnetic forces are present in every device. The link between electricity and magnets is critical to understand when dealing with such objects. The motions of electrons produce an invisible field of energy as they move around a nucleus at random, while in materials such as iron, they may travel in one course (Sibley, 2021). This notion implies that all objects possess the described force and may create a current that transfers energy through space. Electric charges affect free electrons in materials, creating an imbalance and electromagnetic fields (EMFs), while magnetic fields (MFs) induce currents by attracting or aversing subatomic particles in a direction defined by the poles (Sibley, 2021). Therefore, MFs can manipulate electricity and vice versa, linking both terms closely together. However, there is an essential difference between the terms, as magnetism refers to a movement that does not require electricity, while EMFs always consists of both electric and magnetic components (Sibley, 2021). This idea leads to the described separation of EMFs and MFs, although it remains vital to review both topics simultaneously.
Voltage in a circuit is affected by EMFs and is either reduced or increased by their influence. Supplied voltage depends on induction, which implies the movement of an MF that passes through a conductor (Sibley, 2021). Depending on the size of an MF and the length of its flux lines, voltage is changed to reflect these parameters. In conclusion, magnetism and electromagnetism are nearly inseparable in physics and often presented as a single subject. These forces are created with the same type of motion that creates a field emanating from a charged object.
