# Magnets and Magnetism Worksheet Answers

Magnetic fields are caused by moving charges. All magnets have a north pole and a south pole. Like poles attract, and unlike polarity repel. A compass needle points north. A magnetic field is created when a moving charge is moved in one direction. A current flowing through a wire forms a circular pattern around the wire. The direction of the magnetic field depends on the direction of the current.

When the iron ring touches a brush, an electrical charge is transferred between the two brushes. The magnets attract the iron. When the two iron filings touch, a magnetic field is created around the iron ring. When the two ends of the solenoid touch, the needle will deflect to the north. In the same way, an electric current can travel from the house to the magnetic field.

A coiled wire placed near a magnet causes the wire to spin. This is used for mechanical work. The same principle applies to the use of electromagnets, which can be found in computer disc drives, speakers, power windows, and locks. These are the strongest parts of a magnet. A coiled wire close to a magnet can also attract iron. A tin can be made of steel, aluminum, and nickel, which attract metal to another.

A simple demonstration of the power of electromagnets is to create a magnetic field using an iron ring and a wire with the opposite ends. When an iron ring is placed near a magnetic field, the metal ring spins. An electrical current can be passed through the wire and can cause the solenoid needle to deflect to the north. A metal ring and a steel ring can also create an electrical current.

An electromagnet is a device with a magnetic field that attracts objects to its poles. A magnet is an electromagnet when two charges move near each other. It can be used to spin a piece of metal, such as a coiled iron ring. Other devices that use electromagnets include speakers, power windows, and locks. Essentially, an electromagnet can be used to turn on an electrical current.

The magnetic field of an iron ring is formed by an electric current. An iron ring can be used to make a magnet. It is a device that attracts objects to its magnetic field. An electric current is passed through it, and when the brushes touch each other, the iron rings touch the brushes. Depending on the strength of the magnetic field, the iron ring can be positioned northward and southward.

In addition to attracting iron, magnets also attract other metals. The two poles of a magnet are opposite to one another. They are in opposite directions and point towards the magnetic north pole of the earth. The magnetic field of a magnet is created when the two magnetic poles of a magnet are in the same plane. However, a magnet can attract many different objects. Various metals are attracting and repelling.

An iron ring is a powerful magnet. It attracts iron. It can also attract a steel ball. A magnet can also attract another metal. For example, a magnet can attract an iron ball if it touches a steel ball. An iron ring is a great example of a magnetic field. If an object is close to an iron ring, it will be attracted to the magnet.

A magnetic field can be visualized by examining a magnet. If a magnet attracts an object, it creates an electromagnetic field. In addition to this, a magnet can also attract another metal. A magnetic field can be viewed as an electromagnetic force that can draw an object to itself. If an electric current is applied to an iron ring, it will cause the coil to spin. A small iron ring is a stronger magnet than an iron ring.

An electromagnet is a permanent magnet. It is a small magnet that keeps the coil rotating. It can attract an object by attracting another object. For example, an electric motor can be controlled by changing the direction of its current. Its purpose is to rotate a magnetic object. In addition, a magnetic field can also be detected in the air. Besides, it can also be detected by a magnetic sensor.
