Yes. That's how the navigator of an airplane in flight is able to use a magnetic compass.
Yes, electrostatic forces can act over a distance. These forces result from the interaction between electrical charges and can cause attraction or repulsion between charged particles, even when they are not in direct physical contact. The strength of the force decreases as the distance between the charges increases.
The driving distance between Canberra and Melbourne is approximately 665 km. The driving time would be approximately 7 hours 45 minutes if you were to drive non-stop in good driving conditions. (The driving time does not take into consideration conditions such as weather, road work and rush hour traffic in urban areas.)
Two forces that can act over a distance are gravitational force, which is the force of attraction between two objects with mass, and electromagnetic force, which is a fundamental force responsible for interactions between charged particles.
The magnetic force is considered an action-at-a-distance force because it can act on objects without physical contact between them. It can attract or repel objects at a distance through magnetic fields, similar to how gravitational forces act between objects without the need for direct contact.
Magnetic forces act between objects that have a magnetic field, such as between two magnets or between a magnet and magnetic material like iron. The forces are strongest at the poles of the magnets and decrease with distance.
Canberra became the capital of Australia in 1927 and is located in the the Australian Capital Territory (ACT). A project to find a national capital was commenced in the 1890s prior to Federation. The on-going rivalry between Sydney and Melbourne prohibited either city from consideration as the national capital. It was decided that, following Federation in 1901, the nation's capital should be situated between the two cities. A location was chosen which was 248km from Sydney and 483km from Melbourne.

Some forces act at a distance and thus do not require direct contact between objects. Examples include gravitational and electromagnetic forces. These forces can influence objects without physical contact due to their field-like nature.
For gravity to act on every object, two criteria must be met: mass and distance. Every object must have mass, which is a measure of how much matter it contains. Gravity also depends on the distance between objects, with the force decreasing as distance increases.
