Flowers Use Electric Energy to Attract Bees


Flowers with electric field attracts bees < Acumagnet > 02/24 09:48:38

The bees create negative charge as they fly, and flowers create positive. When a bee gets near flower, the attraction occurs and pollen is attached to the bee as a result. The pollen snaps onto the bee. The bees use the electric field as a way to detect nectar.

Magnets are said to disrupt the trajectory of the charged ion. What effect would occur if magnets were lined around the entrance to a beehive? Would it affect the pollen on the bees bodies? Could the pollen start to collect near the entrance as a result of the ion manipulation?

There are two forces at work here < nowgenesays > 02/24 10:01:52

1. Electro-static charge
2. Magnetic field

In your first paragraph, you described how electrical charges effect the bee’s attraction to flowers, as well as pollen’s attraction to the bee. Magnetism is not involved here.

In your second paragraph, you described how magnets effect the trajectory of the charged ion. That same principal allows a CRT to function. That’s because a magnetic field can deflect an electron beam (as shown here):

But the magnet itself is NOT attracting pollen. The magnetic field is merely DISRUPTING electrical forces, thereby interfering with any attractions that would normally be present in those electrical fields.

I don’t understand the disrupt part < Acumagnet > 02/24 10:13:59

Could this disrupt effect also be known as the eddy effect? I believe the eddy effect balances electrical pulses. Perhaps the bees reduce the charge when they fly close to the magnetic field?

Would lining the entrance hole with copper? I read that copper kills slugs because they build up an electrical charge as they slide across it which eventually kills them.

I was thinking about the effects of magnets and copper at the entrance hole and what they could do to a bee. Every bee would touch it as they leave and return. If nothing else, the copper kills bacteria, so that could be the only benefit.

Disrupt = I don’t know what’s happening, really < fun_with_magnets > 02/24 11:25:28

Simply stated, charging body moving through a magnetic field travels in a spiral. OR:

“The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule. The force is given by the charge times the vector product of velocity and magnetic field. ”

The bees would not be moving fast enough at the entrance to the hive for the magnet to affect the charged pollen. Read up on cross product.

Two similar but different phenomena < nowgenesays > 02/24 11:44:05

Since I used the word “disrupt”, let me describe in greater detail.

First let’s bring back that image of a CRT:

The cathode on the back of the tube (left on image) shoots a beam of electrons (shown in yellow) towards the front of the tube (right on image) [because of the positive electrical charge on front of tube]. But notice that the yellow beam of electrons is bent. That’s because of “vertical deflection” in this example. What’s not clearly shown in the diagram is that “vertical deflection” & “horizontal deflection” is caused by electro-magnets.

The point here is that a magnetic field can change the shape of an electrical field. That’s why I said “The magnetic field is merely DISRUPTING electrical forces“.

The “eddy effect” is slightly different. To understand the eddy effect, you first need to understand two other principals (that are opposite each other.

1. When copper passes through a magnetic field, electricity is generated [in that copper].

That’s how a generator works – you add mechanical energy, and get electricity as a result.

2. When electricity passes through copper, a magnetic field is generated.

That’s how a motor works – you pump in electrical energy, and get mechanical movement as a result (since the magnetic field around an electro-magnet interacts with the magnetic fields around permanent magnets).

The eddy effect involves both principals working together. As a magnet descends through a copper tube, electricity is generated inside the copper. In turn, the electricity inside the copper generates it’s own magnetic field. The magnetic field generated in the copper interacts with the magnetic field of the permanent magnet, and slows it’s descent.

This video clearly explains the “eddy effect”:

Bending mostly occurs close to magnets < nowgenesays > 02/24 12:25:12

Notice [in the previous CRT diagram] that the yellow electron beam is not curved. Instead, it starts as one straight line, then it’s direction is “bent” as it passes between the deflectors (electo-magnets), and then it emerges as another straight line. In the case of a CRT, the beam of electrons is targeted to the phosphorous coating on the front of the picture tube. So the magnetic field generated by the electro-magnets (labeled as “deflector”) is only strong enough to bend the beam towards it’s intended target.

Although the magnetic field is a continuously bent…

…most bending effect on an electron beam only occurs when the beam passes close by the magnet.

(I’m not sure about your last statement.)

It shows vertical deflection occurring between horizontal deflectors:
