Yes, an electromagnetic field can repel physical objects if the objects are ferromagnetic (contain iron) and the field is strong enough to overcome the force of gravity or any other forces acting on the objects. This is the principle behind magnetic levitation and magnetic repulsion systems.
What else can I help you with?
Why can magnets attract objects without touching them?
Magnets create a magnetic field around them that can exert a force on other magnetic materials without physical contact. This force is the result of the alignment of magnetic domains in both the magnet and the object being attracted, causing them to be pulled together.
How do electro magnets work and what are their applications in modern technology?
Electromagnets work by using electricity to create a magnetic field. This magnetic field can attract or repel objects made of magnetic materials. In modern technology, electromagnets are used in a variety of applications such as MRI machines, speakers, electric motors, and magnetic levitation trains.
What form of energy attracts objects that are made out of iron?
Magnetic energy attracts objects made of iron. When a magnetic field is present, objects containing iron are drawn towards the source of the magnetic field.
What do we call the force that surrounds magnetic objects?
The force that surrounds magnetic objects is called a magnetic field. This field is responsible for the attractive and repulsive forces experienced between magnets and magnetic materials.
What are all charged objects surrounded by?
Charged objects are surrounded by an electric field, which exerts a force on other charged objects within its influence. The direction and strength of the electric field depend on the magnitude and sign of the charge creating it.
What is electro -magnetic force?
Magnetic force is present around the electric field which is also known as electro-magnetic field.
What is the EMF for DC machines?
Electro Magnetic Field

How electro magnet work?
ANY electrical current will be surrounded by a magnetic field. In an electromagnet, this magnetic field is often amplified by an iron core.
Can magnets attract objects without touching them?
A magnet has a magnetic field around it. The magnetic field causes a magnetic force that can attract objects to the magnet.
What form of energy attracts objects that are made out of iron?
Magnetic energy attracts objects made of iron. When a magnetic field is present, objects containing iron are drawn towards the source of the magnetic field.

Physical significance of magnetic dipole moment?
The magnetic dipole moment represents the strength and orientation of a magnetic field produced by a current loop or a magnet. It is a measure of the ability of an object to interact with an external magnetic field. This property is fundamental in understanding the behavior of magnetic materials and the interactions between magnetic objects.
What are all charged objects surrounded by?
Charged objects are surrounded by an electric field, which exerts a force on other charged objects within its influence. The direction and strength of the electric field depend on the magnitude and sign of the charge creating it.
What and makes magnetic objects different form non magnetic objects?
Magnetic objects have domains of aligned magnetic moments that create a magnetic field, while non-magnetic objects have randomly oriented magnetic moments that cancel each other out. Additionally, magnetic objects can be attracted to or repelled by magnets, whereas non-magnetic objects are not affected by magnetic fields.
How does an electro-magnetic wave get its name?
Electricity and magnetism are closely related. When you pass a current through a conductor, a magnetic field is produced. In continuously changing current, a disturbance is caused in the form of a wave, in both the magnetic field and electrostatic field. Hence electro-magnetic. Examples of this wave extends across a whole spectrum, including radio waves, x-rays and light.
