A looped wire would have a stronger magnetic field because a looped wire is closer to the magnet all the way aroud.

Inside a current carrying loop of wire there are mutually reinforcing force fields coming from all sides of the loop; with a straight wire, the force field comes from only one direction.

How does distance between two objects affect the way they move?

If the objects are not tied together, and if the gravitational forces between them are negligible in their current environment, then the distance between them has no effect whatsoever on their motion.


Why does the voltage need to be so high in a power station?

In long range,electric current can flow only when the wires are given high voltage.The voltage is about 20-30kV.eg.lightning. ---------------------------------------- Current of any voltage can flow in a wire. However, the larger the current is, the larger the resistance to flow and the greater the loss of energy during transmission. Therefore, to transfer the same amount of energy per second (power) without as much loss of energy due to resistance, current needs to be lowered by increasing the voltage since Power = Current * Voltage.


What gets used up in an electric circuit current or energy?

One of Kierchieff's laws tell us that the more wattage (energy) consumed by an electrical device in a circuit, the larger the voltage difference that exists across the device and the greater the current flowing through it. The energy consumed is directly proportional to the Impedance of the electrical device but is more importantly proportional to the square of the current. WATTS=VOLTS X AMPERES= RESISTANCE (IMPEDANCE) X AMPERES X AMPERES A Circuit with Current but without resistance would exhibit no energy at all.


Which is greater 0.6cm or 8mm?

8mm is greater.


Why is a greater amount of force needed to accelerate a truck than a jeepney even if they are running with the same velocity?

The truck has a greater mass and therefore a greater amount of inertia to overcome. To accelerate a greater mass requires a greater force.

The magnetic field strength inside a current-carrying coil will be greater if the coil encloses a?

If the coil encloses an iron rod, then the magnetic field strength inside a current-carrying coil will be increased. This occurs because the air path in the coil is made shorter by putting in the rod. This in turn causes an increase in the field.


How the magnetic field around a solenoid can be strengthened?

The strength of the magnetic field produced by a current carrying solenoid depends on:The number of turns - larger the number of turns, greater is the magnetism produced.The strength of the current - when current increases, magnetism also increases.Nature of 'core-material' used in making the solenoid - if we use soft-iron as a core for the solenoid, then it produces the strongest magnetism.


How does current flows when inductor n capacitor r in series?

The stronger the magnetic field on your inductor the greater amount of current you will have flowing through your series circuit.


Is magnetic field strength directly proportional to the coil or the current?

The strength of a magnetic field won't be directly proportional to the turns in the coil. It is more correct to say that field strength is directly proportional to current through the windings of the coil. There are some "limiting factors" that will not allow this to be a hard and fast rule, but it is essentially correct.AnswerMagnetic field strength (symbol: H) is defined as the magnetomotive force per unit length of a magnetic circuit. As magnetomotive force is the product of the current flowing through a winding and the number of turns, then, yes, magnetic field strength is proportional to both the current and the number of turns -but this is ONLY true over the straight part of the magnetisation curve (i.e. before it goes into saturation).


Why do factors effect electromagnets?

The factors that affect the power of electromagnets are: the current (amperes), the amount of coils, and whether a soft iron core is present. These affect the electromagnet because the current is what provided the electrical energy which created the magnetic field, and so the greater the current, the stronger the magnetic field; the amount of coils is a measure of the resistance provided by the wire, and so the greater that is, the more electrical energy is being used to strengthen the magnetic field; finally, the soft iron core further strengthens the magnetic field as it can be temporarily magnified, so it will become a magnet itself.


What happens to the strength of an electromagnet when the voltage in the coils of the solenoid is decreased?

The greater the current in the coil, the stronger the magnetic field will grow. Conversely, lowering the battery voltage decreases the current, weakening the field.


What do you mean by eddy current loss?

Eddy currents are currents induced in conductors to oppose the change in flux that generated them. It is caused when a conductor is exposed to a changing magnetic field due to relative motion of the field source and conductor, or due to variations of the field with time. This can cause a circulating flow of electrons, or a current, within the body of the conductor. These circulating eddies of current create induced magnetic fields that oppose the change of the original magnetic field due to Lenz's law, causing repulsive or drag forces between the conductor and the magnet. The stronger the applied magnetic field, or the greater the electrical conductivity of the conductor, or the faster the field that the conductor is exposed to changes, then the greater the currents that are developed and the greater the opposing field.

What does voltage do to electrons?

It causes them to move. The greater the voltage applied, the greater the current generated (for the same resistive load), and so the more electrons move.


What is the centimeters when the magnet and metal paper clip is a strong magnetic?

The least # of centimeters, the greater the magnetic attraction.


Is the magnetic field strong at the magnetic poles?

this is because the concentration of domains is greater at poles as compared to inside of magnet
