What makes electromagnets useful?
Electromagnets are useful because some machines need magnets that can stop being magnetic. In junkyards, some machines need to pick up metallic objects, so they need magnets that can turn on and off, which is where a electromagnet becomes useful.
What makes characteristic properties useful?
Well, they help characterize objects, don't they?
The characteristic of the radioactive isotope uranium-238 that makes this isotope useful for accurately dating the age of a rock is the isotope's BLANK?
The characteristic of the uranium-238 isotope that makes it useful for dating rocks is its long half-life of about 4.5 billion years. This allows for accurate dating of rocks that are billions of years old.
What characteristic of radio waves makes them useful for determining the shape of the galaxies?
Radio waves can penetrate interstellar gas and dust without being scattered or absorbed

What advantage do electromagnets have over other magnets?
Electromagnets can be turned on and off by controlling the flow of electricity, while permanent magnets have a fixed magnetic field. This makes electromagnets more versatile and suitable for a wider range of applications. Additionally, electromagnets can produce a stronger magnetic field than most permanent magnets.
What features of ms power point makes it very useful?
The feature of MS power point which makes it unique is it's simplicity. It can provide simple and high functioning features.
What are electromagnets more useful than permanent magnets?
Electromagnets are more versatile because their magnetic field can be easily controlled by changing the amount of current flowing through them. This makes them suitable for applications such as lifting heavy objects in scrapyards, magnetic resonance imaging (MRI) machines, and electric generators. In contrast, permanent magnets have a fixed magnetic field strength that cannot be easily altered.
What has magnetic properteis and can be controlled by a switch?
Electromagnets exhibit magnetic properties and can be controlled by a switch. When an electric current flows through a coil of wire wrapped around a ferromagnetic core, it generates a magnetic field; turning off the current disables the magnetism. This ability to toggle the magnetic field on and off makes electromagnets useful in various applications, including electric motors, relays, and magnetic locks.
Why is simple interest useful in financial calculations?
Simple interest is useful in financial calculations because it is easy to understand and calculate. It is based on a fixed percentage of the principal amount, making it straightforward to determine how much interest will be earned or paid over a certain period of time. This makes it a useful tool for budgeting, planning investments, and understanding the cost of borrowing money.
What devices makes use of electromagnet?
Devices that make use of electromagnets include electric motors, doorbells, MRI machines, loudspeakers, and generators. Electromagnets are also used in car starters, relays, and magnetic levitation trains.
Why are contours useful?
Why is any car useful? Your question makes no sense.
