Request an appointment. Familial adenomatous polyposis (FAP) is a rare, inherited condition that causes extra tissue (polyps) to form in your large intestine (colon) and rectum. Polyps can also occur in the upper gastrointestinal tract, especially the upper part of your small intestine (duodenum).
An iron core will produce the strongest magnet. By increasing the size of the core you also increase the strength of the electromagnet. Compare the diagrams. Note: Look at the amount of coils, the size and number of the power source.
The factors that affect the strength of an electromagnet are: Number of coils of wire. Number/voltage of batteries. Properties of the core. Number/voltage of batteries. By using a battery with a greater voltage the strength is increased. You can also add more batteries to a series circuit to increase the strength. What factors affect the strength of an electromagnet? By increasing the number of coils of wire around an object can increase the strength of the electromagnet.
