I can confirm this information because I had this same question for home work so I can confirm the answer is true.
What else can I help you with?
How can an electromagnet attract plastic?
A pure hydrocarbon/fluorocarbon plastic contains no ferromagnetic material, so it will not be influenced by a magnet. If a plastic is loaded with ferromagnetic material (such as iron particles), then it will be influenced by an electromagnet. Ceramic materials loaded with ferromagentic materials, known as ferrites, are widely used in electrical and electronic equipment.
What is a magnetic force?
A magnet creates a magnetic field, often mistakenly referred to as a magnetic force. The actual force felt by a charged particle in a magnetic field (or electric field) is called the Lorentz force.
The space in which the force of a magnet can act is called a?
magnetic field. This is the area around a magnet where its magnetic influence or force can be detected or felt.
When a charge moves in the same direction as the magnetic field lines the magnetic force is?
Perpendicular to both the current and the magnetic field.
When a magnetic field is parallel to a current-carrying wire what is the force on the wire?
When a magnetic field is parallel to a current-carrying wire, there is no force acting on the wire. This is because the magnetic force on a current-carrying wire is perpendicular to both the current and the magnetic field.
What True or false magnetic force is a gravitational force?
False. Magnetic force and gravitational force are two distinct types of forces. Gravitational force is the force of attraction between objects due to their mass, while magnetic force is the force between magnets or between a magnet and a magnetic material.
Magnetism is a contact force because magnets make contact true or false?
False. Magnetism is not a contact force. It can act at a distance, meaning magnets can exert forces on each other without physical contact. This is due to their magnetic fields interacting with each other.
True or false are Magnetic poles called domains?
False. Magnetic poles and domains are different concepts. Magnetic poles refer to the regions of a magnet where the magnetic force is concentrated, while domains are regions within a magnetic material where the magnetic moments of atoms are aligned in the same direction.
When a wire with a current is placed in a magnetic field electrical energy is transformed into mechanical energy true or false?
False. When a wire with a current is placed in a magnetic field, the interaction between the magnetic field and the current in the wire creates a force known as the Lorentz force. This force is responsible for generating mechanical motion, not transforming electrical energy into mechanical energy.
True or false any material that exerts magnetic force is considered a magnet?
It is true that materials that exert magnetic forces are considered magnets. This is the case since it shows they have magnetic field lines that may have been induced or were naturally present in the materials.
Magnetic forces can repel without touching True or false?
True. Magnetic forces can repel objects without them physically touching because the magnetic fields generated by the objects interact to create a repelling force.
True or false that the further apart two magnets are from one another the stronger the forces that attract or repeal the magnet?
False. The magnetic force of attraction or repulsion between the magnetic poles is inversely proportional to the square of the distance between the poles. So farther apart two magnets the force between them becomes weaker.
What is the relationship between a magentic force and a magnetic field?
A magnetic force is the exertion of a force on a magnetic object due to the presence of a magnetic field. The strength and direction of the magnetic force depend on the strength and orientation of the magnetic field. In essence, a magnetic field produces the magnetic force that acts on magnetic objects within its influence.
Is magnetic force?
Magnetic force is the force exerted between magnetic poles, producing magnetization of force, either of attraction or of repulsion.
What force creates a magnetic force?
Typically, an electric current creates a magnetic force. Also, magnetic domains aligned correctly and properly can cause a magnetic force.
What is the relationship between magnetic force and magnetic field?
Magnetic force is the force experienced by a magnetic object when placed in a magnetic field. The strength and direction of the force depend on the characteristics of the object and the field. The magnetic field is the region around a magnetic object or current-carrying conductor where another magnetic object experiences a magnetic force.
How does length of spring coil affect the force constant?
The force constant is unaffected; It is a constant.
