Do Magnets Affect Batteries?

A magnet stored next to the battery does not have any effect on them.

However, there are incidences when a magnet can affect a battery, and the extent of the impact depends on the type of battery in question. The ampere law states that magnetism and electricity are closely correlated. This law is a physical law that outlines how electromagnets are produced by passing a current via a wire to form an electric field.


The reverse is also true; a magnetic field can also generate a current via induction that can drain the battery of any electric device. However, while every current can cause a magnetic field, only a change in magnetic strength or the flux can produce a current as per Faraday’s law.

Thus, a static magnetic field can only lead to battery drainage for a second, but this is not enough to cause any noticeable impact on the batteries. Generally, magnets do not appear to affect batteries significantly or adversely except for special situations like a freak accident.


What happens when you put a battery on a magnet

When you put a battery on a magnet, the wire will touch on top of the magnet and the battery. Once the wire touches, it makes a circuit that allows electrons to flow, which is called the current. There will also be a magnetic field generated because of the magnet at the bottom of the battery.

Do magnets affect cell phones?

It sounds to be quite clear and simple that your phone might be at risk of being affected by the magnet, or what is the secret behind the magnet being away from the cell phone?

You have to know that your phone won’t be interfered with by a magnet fully, but magnets can slightly affect phones in one way or the other.

The idea of keeping your phone away from magnets is from far at the beginning and the development of gadget technologies in the early days. Individuals with devices like computers and televisions were cautioned not to keep such gadgets near magnets. Likewise, phones fall under advanced technology on gadgets.

Magnets affect phones differently. First, it depends on the nature or design of the phone and secondly, how you use the phone. For example, smartphone apps can be tempered by the magnetic fields that can malfunction the phone. Magnets affect the device by magnetizing some steel materials inside the phone, making them corrupt and hard to use, such as Google Maps.

The smartphones’ cameras can also become stabilized if the phone is near the magnet, as their rear autofocus may start functioning with difficulties. Also, when it comes to the battery part of the cell phone, magnets can affect them.

Less powerful magnets with little magnetic field effect do not harm your phone’s battery. However, magnets with a strong magnetic field may affect the battery significantly. The battery is affected in a way that it works harder in supplying the required voltage to the cell phone. Therefore, strong magnets will drain your battery more and increase the wearing out, leading to a short lifespan.

Do magnets affect watch batteries?

You may have heard stories that magnets can make your watch gain, potentially stop your watch or lose time; this is not a myth but a fact. A watch is made of materials like metal which are magnetic. This means they can be attracted or affected by magnetic fields. For example, when iron and steel gears come closer to a magnetic effect inside the watch, they are charged and may pull in different directions. Now, this is where gaining or slowing of time comes in but leave alone that as the magnet will affect your watch’s time and battery.

Watch batteries are designed with a metal shell that protects the inner contents. Around the metal shell, there is an iron charge that can be affected by any magnetic field. Magnets with strong magnetic fields cause the battery to aggregate by shortening the iron charges, leading to battery draining.


Do magnets affect lithium batteries?

Magnets do not have any adverse effects on lithium batteries. However, improper storage of a lithium battery might lead to its damage. Lithium batteries contain lithium ions which is one of the powerful batteries. The battery can run powerful devices. Lithium batteries are made with carbon or graphite, and lithium carbon is often a low-grade music field. This means that the magnet cannot affect a lithium battery’s performance.

However, while this might be true, high power magnets such as those used in scientific experiments can significantly affect a lithium battery. This is why it is not advisable to get to a scientific environment with an electric device. Other powerful magnets that can affect a lithium battery hemodynamic silver magnets but are rare.

Do magnets affect alkaline batteries?

Allkaline batteries are not affected in any way by magnets, even if they are stored together. However, there are rare cases. For instance, if the battery contains iron in the outer coat, the iron can make the battery aggregate throughout the magnet, making them short of one another hence making them drained. Moreover, storing and powerful magnets can significantly affect the functioning of these batteries.

Magnets do not affect any battery, whether a cell phone, lithium, watch, or alkaline battery. Although there might be effects in some cases, they are not such significant unless in a freak accident.

For example, a magnet can clasp to the top end in an accident since the gap between positive and negative is small. If it does so, it will connect the positive and negative, which can cause a short circuit or even fire.
