Is magnetic field stronger than electric?
Electric fields are strongest close to a charge or charged conductor, and their strength rapidly diminishes with distance from it.
In contrast to electric fields, a magnetic field is only produced once a device is switched on and current flows.
The higher the current, the greater the strength of the magnetic field..
What is the difference between electric and magnetic forces?
Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). … Electric field points in the direction of the force experienced by a positive charge.
What is the strongest magnetic force?
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
What makes an electric force stronger?
The strength of the electric force between any two charged objects depends on the amount of charge that each object contains and on the distance between the two charges. As the amount of charge gets bigger, the force gets bigger, and as the distance between the two charges gets larger, the force gets smaller.
Does EMF go through walls?
EMF Protection Tip 1 – Understand about EMF Penetration Low frequency radiation does not bounce off walls or floors – it just goes straight through. In fact, it will penetrate anything – brick, metal, concrete, and you – without any trouble. Nothing blocks low-frequency EMF.
Can a magnetic field exist without an electric field?
No you can have a magnetic field without an electric field. Consider a rod with an equal number of positive and negative charges (such that they are equally spaced). Let the positive move to the left with speed v and the negative to the right with speed v. This will result in a magnetic field but no electric field.
